Pennsylvania near Essay Example for Free

Pennsylvania near Essay Mining has been going on for a quite a long time in the whole world. It is worth noting that quarrying is an activity which is primarily aimed at extracting materials such as granite, limestone, slate and clay for various construction uses. On the same note, quarrying in Bangor has been done for more than a hundreds years due to the existence of karts topology. Bangor is located in eastern part of Pennsylvania near Pocono Mountains and West of Delaware Water Gap. It bears noting that Karts topology which has dominated this area is formed on limestone rocks by dissolution, includes underground streams, caves and beautiful sceneries (Langer, 2001). All these sceneries have been destroyed by quarrying impacts such as air pollution, noise pollution, and damage to biodiversity, land disturbance and heavy metal / toxins release. The neighborhood has for along time experienced a lot of difficulties in dealing with these impacts which are controllable though have far reaching effects.   Quarrying of Carbonate and other Rocks Since smaller and regular shaped stone products are required, large blocks of stone are extracted to provide a room for modifications. According to Langer (2001) a block of stone is cut from the bedrock mass by separating the block on all vertical sides then undercut the block or break the block away from the bedrock mass (p. 6). The major methods of quarrying are channel cutting and drilling and broaching. In channel cutting a multiple chisel-edged channeling machine cuts a rock into bars while in case of drilling and broaching method, a drilling machine drills many deep holes in a coordinated pattern (Langer, 2001). A broaching tool is then used to curve and chops the gaps between the drill holes which free the required block from the underlying bedrock mass (Langer, 2001). It is a requirement that the cutting be frequently sharpened for effectiveness Line drilling and blasting are the most modern methods used in quarrying in areas of Bangor. Line drilling involves the drilling holes in an overlapping manner and then sewing the stone using a wire saw or a chain saw (Langer, 2001). Blasting generally applies the use of explosives which break the stone blocks and produce small stones for crushing. This therefore implies that blasting cannot be applied in quarry when a certain shape of rock is desired (Langer, 2001). Quarrying affects the surrounding area and the immediate wildlife with numerous environmental damages. 3. 0 Air pollution All forms quarrying are capable of releasing dust which pollutes the air. Drilling and blasting are known to produce the most of the dust that affect the surrounding air (Langer, 2001). Clearing the forest or vegetation cover can also produce a considerable amount of dust. Another source of dust production is during the removal of soil cover for development of the quarry. Some of environmental factors that affect the concentration of dust include local microclimate condition, the dust particle size and the chemistry of the dust itself (Langer, 2001). Take for example a quarry like Capozzolo Slate Company which produces highly alkaline and reactive dusts from its mines and factory (Langer, 2001). If a coal mine is taken as a point of consideration, it produces a lot of heavy acidic dust. Air pollution from quarry dust becomes a nuisance over time since it deposits a heavy layer on plants and other surfaces it comes into contact with. It has far reaching effects on health of individuals by causing respiratory complications and eye problems. With respect to plants, dust coat causes the blockage of their internal structures which leads to and damaging of leaves and their cuticles (Langer, 2001). The long term survival of the plant is generally interfered with by the dust. 4. 0 Noise pollution Noise pollution develops from quarrying activities which start from the land clearance to the transportation of the final product of the quarry (Langer, 2001). The initial activities that produce noise pollution include those that are aimed at establishing access roads and rail connection, the quarry compound and also stone processing facility. The following procedure of exposing the stone mass to be extracted by removing all top soil using earth movers produces a lot of noise. In addition, the use of hydraulic excavators produces noise. Likewise, the drilling machines and blasting activities equally produce very loud noise (Langer, 2001). During the transportation of final product using heavy and powerful machines, truck traffic contributes to the production of noise (Langer, 2001). Additionally, the processing facility produces a lot of noise since crushing requires a lot of power. Consequently, the noise affects the surrounding wildlife and humans. 5. 0 Damage to biodiversity The major negative impacts of quarrying on the entire environment have been damage to biodiversity. Biodiversity basically refers to a wide range of living creatures, including mammals, fish, insects, invertebrates, reptiles, birds, plants, and micro-organisms (Langer, 2001). Quarrying destroys the ecosystem and all the species that are support. Moreover, the ecosystems are not only destroyed by the direct removal of the whole ecosystem but also indirectly by affecting and damaging related environment condition of the entire place (Langer, 2001). There are changes to underground water and surface water which cause many ecosystems to dry up while some experience flooding. Besides, the quality of water flowing downstream is compromised by the quarrying activities. On the same note, the water which comes into contact with the quarry by products is hard to purify since it cannot be filtered. Underground water is the most affected if quarrying activities interfere with the sinkholes by causing them to collapse. Ground-water pumping causes change of the flow of surface water. The large amounts of soil carried to the rivers cause result in a lot of silt deposits that pollute water systems thus killing animals. Quarrying in the Bangor zone has resulted increase of water runoff to some parts while other parts have been experiencing reduced water quality. Generally, quarrying causes the lowering of the ground water table by forcing it to go under the rock interface (Langer, 2001). The pumping of water out of the quarry may lead to high fluctuation of water ground water levels which may lead to drying up of the surrounding underground water systems. 6. 0 Land disturbance The land terrain is largely affected by the excavation activities and the damping of the waste soil. In to the bargain is the fact that the activities of making new rail line and roads cause a lot of soil movement which affects the natural terrain of the ground (Langer, 2001). Moreover, the land which is left after quarrying has stopped cannot be used economically through agricultural or commercial activities. 7. 0 Quarry Waste Just like many of the man-made mining activities, quarrying engages the production of considerable large amounts of wastes (Langer, 2001). A few quarries produce small amounts of permanent waste products with examples of sand and gravel quarries while others produce a large amount of waste material which includes clay and silt (Langer, 2001). The quarry wastes does note pose a big dander to the environment though it still have the potential for damage to the environment by contaminating any water that it comes into contact with. The quarry leaves permanent scars and massive footprints in landscapes (Langer, 2001). The abandoning of the quarry site leaves Lange trunks of landmass unsuitable for other uses. 8. 0 Heavy metal and toxins release Quarrying may release a lot of heavy metal and toxins to the environment that affect people’s health negatively and cause far reaching impacts on the surrounding ecosystem if it is conducted in areas that have harmful minerals (Langer, 2001). The release of harmful materials such as silica which is found in rocks enters the lungs , thus causing silicosis which is deadly as it can rip off the lungs. This may happen when little fragments silica rise as part of dust which is later breathed in through the nose. Another common effect of toxins is experienced when toxins are suspected to have been sipped in the water, which may lead an entire neighbourhood to go far away for search of clean and pure water. 9. 0 Recommendations The first measures to curb air pollution from quarrying activities should focus on the developing a forest cover that can contain the dust (Urich, 2002). Forest would help in increasing percolation and preventing soil erosion due to pumping of water out of the quarry site. Watering the roads that are used by the transporting track is also very useful (Urich, 2002). The quarry operations should be controlled in order to minimize the emission of the heavy dust by using modern technologies such as sawing instead of blasting stones. Land geo-morphological condition should be improved by an importation of other materials to fill the huge holes so as to return the natural ecology. Authorities in Bangor have made a mandatory that a reclamation guide line be included with each application for any quarrying permit (Langer, 2001). Contamination that occur through using abandoned quarry as dumping site can be voided by filling the quarry with soil that is free from any contamination. Moreover, water conservation measures can be applied by constructing stop dams and ponds that act as ground-water recharging sites (Langer, 2001). The surface run-off water is held back and all suspended solids are allowed to sink before entering the hydrological system. Controlling the soil erosion entry to streams by stabilization of exposed soil surface can be achieved by initiating vegetation cover growth on steep sides. Noise pollution can be reduced if the trucks traffic uses well designed road rail network. Better methods of stone extraction should be applied to avoid the production of noise pollution which people associate with quarrying activities. The damage to biodiversity can be lessened by a careful use of machines to avoid affecting a large portion of ecosystem. Land rehabilitation should follow immediately after the quarrying activities are completed (Langer, 2001). The quarry waste should be returned to the exposed hole before leaving the mining site. Finally, water that is drawn from the quarry should not be allowed into streams before its toxic levels being determined and ascertained that the levels are not dangerous. When all these are put into practice, then, the levels of pollution will greatly decrease. References Langer, W. H.

Understanding Of Elemental Cost Analysis Construction Essay

Understanding Of Elemental Cost Analysis Construction Essay The analysis is actually done to be used by the designer and the client for future project and therefore, comparison between two or more buildings can be made. This is brief project cost information gathered from bills of quantities. Apart from the cost analysis, information such a brief project specifications and the overall project information are also included in the ECA. Purpose for ECA To show the cost relationships between several sections/ parts of the building, if there are any. To allow comparisons of cost with other different projects. The cost that is obtained from the cost analysis is insufficient to determine the actual price. It has to take into account the conditions and the details of the project and the quality and quantity of work involved. The cost analysis has been introduced to provide cost information especially for the process of cost planning. The cost analysis is prepared by examining the information of a project which has been planned or constructed in which the bills of quantities have been priced. Therefore, the cost analysis is prepared based on the data received from the successful tender and is not based on the actual sum of the project. However, there are several reasons as to why the cost analysis is not prepared based on the actual cost: The final account is often complex and requires much ttime to analyze the changes in the account. This would result in the decreasing interest of the individual preparing the cost analysis. The preparation of the final account is time consuming due to several reasons and this could result in the cost analysis that is published to be out-dated The historical data for cost planning may not be accurate especially during high inflation (although there are procedures to update this by using indices). It is difficult to make allocations for the increase in cost and contractual claims, which are tailored to the individual elements. Uses of ECA Appreciation It enables clients and designers to know and appreciate how cost is distributed among the functional components of a building and compared to the overall cost of a building. Judgment It enables clients and designers to develop ideas as to how element costs could have been allocated to obtain a more balanced design. This judgement is important to gauge the effectiveness of cost and quality of a building. Belated remedial action Allows remedial action to be taken on receipt of high tender, by revealing the sources of over-expenditure that is by making comparisons between estimated costs and tender price. This will enable belated remedial action to be taken. Planning The cost analysis could be used as a source of cost information to help with the cost planning of future building projects. Abbreviations of forms To simplify the elaboration the author will use the following abbreviations for each form. Form 1 F/1 Form 2 F/2 Form 3 F/3 FORM 1 Information on total project and analyzed building This form is divided into two sections; the first section provides overall information on the project including the location, the client, type of contract etc. The second section provides information and analysis of a single building. Each separate building in the project has a different analysis. The main purpose for the information in Form 1 is to inform the user of the analysis the background of the project and the condition of its price level. This will enable the user to make the necessary adjustments to cater for differences in location, market condition, type of contract, size of contract and specifications of the project. Building type and Code : There are ten classifications on types of building based on (C1/SfB Classification Table 0): 0 : Land, Planning, Landscape 1 : Civil Engineering Work 2 : Transport, Industrial Buildings 3 : Administrative Buildings 4 : Health and Welfare Buildings 5 : Refreshment, Recreation Buildings 6 : Religious Buildings 7 : Educational, Cultural, Scientific Buildings 8 : Residential Buildings 9 : Buildings, Spaces in general Residential Buildings for this project shall be classed under category 8: Buildings, Spaces in general Construction Classes: Construction classes are divided into: A : Reinforced concrete framed construction B : Steel framed construction C : Timber framed construction D : Light framed steel or reinforced concrete construction A 2 321 A 2-storey reinforced concrete framed construction with Gross Floor Area of 321m2 is expressed as follows: The combination of a 2 storey hall building made of reinforced concrete framed construction with Gross Floor Area of 321m2 is expressed as follows: A 321 3- Residential Buildings 3) Job Title: Cadangan Membina Sebuah Banglo 2 Tingkat 4) Location: Daerah Melaka Tengah, Melaka 5) Client: State the type of client whether government, private or semi government-Private 6) Tender date: Date fixed for close of tender- 7/1/2007 INFORMATION ON TOTAL PROJECT 7) Project details and site condition: Explanation shall include the following: Project description Accessibility to site Proximity of other buildings Site topographical and geological conditions Weather Any omission or exclusion from project Example of elaboration: The project comprise the construction and completion of 2 storey banglo and associated ancillary building and external works.

If the number is too many, state at least the lowest five, arranged in descending order. The highest tender value is listed last in the table. Indicate whether tenders were from local builders (L), by international builders (INT), or by joint venture between the two (JV). Refer to tender report. If there are only a few tenders, the list is as follows: RM Int/JV/L 325060 L 320000 L 289500 L 255200 L If the tender list is extensive, the list is as follows : RM Int/JV/L 325060 L 320000 L 289500 L *255200 L *The highest tender value AREAS 11) Gross Floor Area: Method of measurement: Total of all enclosed spaces fulfilling the functional requirements of a building measured to the internal face of enclosing walls (or column, door and the like) Enclosed spaces are defined as all spaces that have a floor and a ceiling and enclosing walls on all sides at full or partial height. Open balustrades, louvers, screens, columns and the like shall be deemed enclosing walls. The gross floor area is measured gross without omission to areas occupied by columns, internal structures or party walls, etc. Areas of lift rooms, tank rooms, engine rooms and the like above main roof are also calculated in GFA. Sloping surfaces such as staircases, galleries, tiered terraces and the like shall be measured flat on plan Spaces that fulfill the functional requirements of building which are not enclosed spaces shall be shown separately under Unenclosed Spaces. B L: Measured gross without omission to areas occupied by columns, staircases and partitions. GFA = 6156m2 Usable area 231 Circulation area 32 Ancillary area 48 Internal divisions 10 GFA 321 FORM 2 Summary of element costs In general, Form 2 shows the systematic breakdown of the costs of elements of a building. There are more than 20 elements in Form 2 and each element is grouped under six group elements (five building groups and one for each group element of external work and preliminary work). Form 2 provides information on the total cost of element, cost per m2 GFA, element unit quantity, element unit rate, ratio of element per m2 GFA, etc which could be used to make a realistic estimate and to prepare the cost plan for new projects. It could also be used to make cost comparisons to ensure cost does not exceed the estimate. Total cost of element (RM): This is the total cost of element and the cost shall follow the List and Contents of element in the Manual. If cost is not related to the said element, (-) shall be inserted. If costs of more than one element are group together, abbreviated notes shall be provided explaining where they are grouped. All the total cost made from Bills of Quantities or calculated by EUQ x EUR. WBLFF : Total cost of element = EUQ x EUR = 136 m2 x 125 = RM 17000.00 Cost/m2 GFA (RM) : Calculated by dividing Total Cost of element with GFA. FRAME : Cost/m2 GFA = Total Cost GFA = RM 255,200 321 m2 = RM 795.016/m2 Element Unit Quantity : All areas shall be the net areas, for example, area for external walls shall omit area of windows and doors, etc. if the quantity is measured in volume (air conditioning spaces) volume is calculated by multiplying the net area with the height of the space to be air conditioned. The abbreviation used is Tm3. All the amount according to taking off or measured through drawings. Element Unit Rate (RM) : Calculated by dividing Total Cost of Element with Element Unit Quantity. It is rounded off to the nearest ringgit. UPPER FLOORS : Element unit rate = Total Cost EUQ = RM 8000.00 185 m2 = 43.24 Element Ratio /m2 GFA : Calculated by dividing Element Unit Quantity with GFA. It is stated to three decimal places. ROOF : Element ratio/m2 GFA = EUQ GFA = 204 m2 321 m2 = 0.636 Reinforced Concrete (m3) : Quantity of reinforced concrete in elements in m3. Reinforcement (kg) : Quantity of reinforcement in kg. Formwork (m2) : Quantity of formwork in m2. FORM 3 Brief Specification Form 3 provides brief information on project specifications based on each element. It briefly describes the various components in each element including the types and quality of materials used. This form provides a brief picture of the building standards and quality and this information is important for cost comparison purposes. It can be refer to the list and contents of elements. Elaborate briefly the specifications according to the elements. All the specification had made from Bills of Quantities. For example of the specification in the elemental cost analysis, in piling works, the specification must have all works related to foundation piling including sheet piling left in and also need to state the system used, whether it is consultants design or otherwise, number, average length and size of the pile. BENEFIT OF ELEMENTAL COST ANALYSIS ECA means the analyze of cost related to the elements, in construction industry a building or any kind of construction we can divide into number of elements, and price of which is related with that element is called as an elemental cost, elemental costs include material costs, labor costs, and sub-contractor overhead and profit. ECA is also important and give benefits due to the companies that can intends to establish a cost information service by setting out goals and collecting information in a planned and systematic way in collecting and spreading information on a number of elemental cost plans available at the moment. These cost plans will further expanded and users will be able to select the database using a range of criteria, among others, type of building, floor area, date, client type, number of stories, location and method of construction. ECA does help a quantity surveyor when it comes to similar projects that are gone to be built next due to its feature that act as a reference about the price or cost information that is useful to prepare a budget plan. Although it is roughly similar, the project that is being compared to previous projects ECA must be in the relevant range of time CONCLUSION The Elemental Cost Analysis (ECA) is relevant to used. The cost analysis is prepared by examining the information of a project which has been planned or constructed in which the bills of quantities have been priced. Therefore, the cost analysis is prepared based on the data received from the successful tender and is not based on the actual sum of the project. That is the price quoted in the Final Account. There is a possibility for some to think that it would be better to analyses the actual cost as compared to the cost predicted in the tender.

Revolutions :: essays research papers

One of the six revolutions that I have studied independently is the Glorious Revolution. The Glorious Revolution took place in England during 1688 to 1689. James II and the Catholic church were in control of the land. The old regime was James II, along with the Catholic church. James II, the second surviving son of Charles I, became king of England in 1685. James crushed two revolts upon his newly found land. One, controlled by his nephew, James Scott, duke of Monmouth, and the other controlled by Archibald Campbell, ninth earl of Argyll. The people were not happy with his performance handling these revolts. James had also ended religious restrictions in 1687, which caused an increase religious tension. On June 10, 1688, William of Orange, later to become William III, was asked to take the throne of England, there by starting the beginning of the revolution. So, now Parliament and William of Orange and his wife Mary and the Catholic church help all the power in England, being the moderates of the revolution. Seeing, as how there were no radicals, there could be no accession of them, nor could there be a reign of terror. Convalescence was reached when Mary and William signed the Declaration of Power. Also, there was now a ruler again. According to Crane Brinton’s "Course That Revolutions Seem To Take", there is only one situation that occurred in the Glorious Revolution. Revolutionaries gain power and seem united. This was shown by how William and Mary and Parliament and the Catholic Church all joined up together to rule over England successfully. None of the other 9 happened during this revolution. I don’t believe that the Glorious Revolution was a revolution at all. First off, the only two things that the people didn’t like were that there was a lot of religious tension and that they thought James was a bad ruler because he was trying to protect the country. I surely hope that Bill Clinton would try to protect us from any outside enemies that tried to take over The United States.

An Indepth Look at HG Wells :: essays papers

An Indepth Look at HG Wells Herbert George Wells was born on September 21, 1866 in Bromley, England, the last of four children. His mother was a house cleaner and his father was a shopkeeper. When he was eight years old, he broke his leg, spent a lot of time reading, and discovered an intense interest in books. At the age of thirteen, his father was injured in an accident so Wells had to leave school and work for a draper. He hated this work and managed to change his employment by working for his uncle and becoming a part-time tutor. This gave him the opportunity to continue his studies in his free time. He finally won a scholarship to The Normal School of Science in London. He worked as a journalist while continuing his education. In 1891, he married his cousin Isabel. In 1894, he and Isabel were divorced and he then married one of his pupils. In 1895, Wells’ first major work was published- Select Conversations with an Uncle. His next book, The Time Machine, also published in 1895, started Wells on his road to success. This book was followed by The Island of Doctor Moreau, in 1896, The Invisible Man, in 1897, and War of the Worlds, in 1898.[1] H.G. Wells was one of the fathers of modern science fiction. He made his reputation as a writer through what he called â€Å"scientific romances†[2], a comment he made about his own science fiction in the 1930’s. However, he himself said that there were radical differences between his science fiction and that of Jules Verne. Wells said that his own work was â€Å"an exercise of the imagination†,[2] as in The Invisible Man and The War of the Worlds. In these books he was not suggesting a serious possibility, just trying to imagine what might happen in a given situation.[2] Jules Verne, on the other hand, based his stories on scientific knowledge. He criticized Wells as basing his books on fantastic, not scientific, assumptions. Wells in some of his books, however, like The Island of Dr. Moreau, did deal with what he called â€Å"Fantasies of possibilities†.[2] Wells also considered himself a philosophical writer and urged that some of his books be taken seriously.

Investigation into wires and resistance Essay

The second two were done using two digital Multimeters so presumably the results on the second two tables are more accurate. Test 1 ammeter/voltmeter: Length of constantan (cm) Potential difference (volts) Current (amps) Resistance (ohms) Ammeter/voltmeter repeat: Length of constantan (cm) Potential difference (volts) Current (amps) Resistance (ohms) Multimeter Test1 Length of constantan (cm) Potential difference (volts) Current (amps) Resistance (ohms)Â   Multimeter repeat: Length of constantan (cm) Potential difference (volts) Current (amps). Resistance (ohms) 1Average resistance over all four tests: Length (cm) Potential Difference (volts) Current (amps) Resistance (ohms). Constantan theory resistances: Using the formula R=E(L/A) I have gathered the exact resistance of a length of SWG24 constantan regardless of any connections or battery faults: Length (m) Resistance (ohms) And this table shows the results of the computer simulation (the computer simulation incorporates the resistance of the connecting wires into the resistance): Length of constantan (cm) Potential difference (volts) Current (amps) Resistance (ohms). We measured the resistance at 0 cm to be 0. 35 ohms. However this cannot possibly be true because the average at 10cm was 0. 2015 and the resistance Analysis This is the average power (IV) plotted against the average resistance: This shows that as the length of the constantan increases more power is required to drive the electricity through the wires and at the same time there is also more opportunity for the power to dissipate as heat and light. This possess is used to good effect in electric fire elements where the wire is coiled to add greater length. My average results of our tests: The results from the preliminary computer tests: Conclusion: From my results and the computer graphs, I can see that the ratio between the length of the wire and its resistance is virtually linear and the theoretical resistance is exactly linier. This makes sense because the constantan wire is of uniform thickness. The resistance on my tests isn’t perfect and this is probably because of the heating effect as explained earlier. Two things that we can see from this graph are that neither the voltage nor the current are linear. This is because the capacity of the batteries are finite and therefore, as the resistance increases to infinity; the current and voltage will level to the capacity of the battery, curving the graph. Still, you wouldn’t expect the voltage or to be linier in a circuit like this because of the internal properties of the batteries and the heating effect of the circuit. Another thing we can see is that as the resistance decreases to zero the current and voltage will decrease to zero. However because the circuit will have it’s own fixed internal resistance including: The battery, the meters, the circuit wires, the contacts etc a theoretical zero resistance is not possible in this circuit. Also as the length of wire decreases to zero the results will become less accurate as the external resistances (mentioned above) become more significant and the temperature rises in the wire are more significant. For example if the internal resistance of the circuit we used totaled 3 ohms and we were testing 0. 001 cm of constantan equaling 0.001958 (if R=E*(L/A) is true) then the total resistance is 3. 001958 ohms, which is way off the actual total. And as you make the circuit smaller there is less resistance so the current is higher meaning that more heat is generated. My resistance results on my hand drawn graph are very nearly linear and that supports my prediction that if you increase the length of wire then the resistance increases. As shown, the line of R=E*(L/A) is linear and if you add the internal resistance of the rest of the circuit to that, it is still linear, but appears lower on the graph. If you take a point on the linear theory line and double its values then those values are true, meaning that in the lines formula X is directly proportionate to Y (this is safe to assume as there are no outside interferences i. e. battery, wires etc only the length and diameter of the constantan). The same is almost true (although shouldn’t be) for my total resistance average line. However, you cannot take the values of a point on the computer line, double them and expect them to be true. This shows that for this line X isn’t directly proportionate to Y but is R=E*(L/A)+the internal resistance of the rest of the circuit. Evaluation Comparing my results to the computer generated ones; I’d say that the experiment went quite well. Although some off connections in our circuit were slightly rusty and damaged the results show that it wasn’t too much of a problem. The range of results obtained was sufficient to form good averages which were comparable to the results obtained from the computer and the results generated by R=E*(L/A), and the results supported my prediction. I believe the results to be accurate because they are fairly consistent with each other. For example on the multimeter test at 50cm the resistance was 0. 9375 ohms and on the repeat I got 0. 88 ohms. This means that there was only a 0. 0575 ohm difference between them. However the results obtained from the voltmeter/ammeter tests were less accurate as it is very hard to read off them to more that 2dp. One strange thing with the results I obtained was that the resistance was much lower than I expected. This is shown by the graph. I would have expected the line to be closer to the computer simulation than the R=E*L/A line because R=E*L/A doesn’t account for resistance where as the computer simulation does. My experiment certainly had resistance in the circuit and yet my experiments line falls almost on top of the one that doesn’t. There are a few ways to explain this. The current in the simulation was lower than the current in real life, the internal resistance of the circuit was very low (which I find hard to believe) or the measurements weren’t accurate enough, either way there is no definite answer. Also on my hand drawn graph there are 3 obvious anomalous results, which didn’t fall on the line of best fit. They are likely to have been caused by poorer measurement, kinks in the wire or a bad connection (more sources of error have already been stated in the plan). However, I think that the evidence is still sufficient to support the conclusion. The way we set up and conducted the experiment was the standard however if I was to do repeat he investigation I would use much shorter circuit wires and use better connections to minimise circuit resistance. It might also be a good idea to use a rectifier instead of batteries so that draining power isn’t an issue. You could also extend the investigation by measuring other variables such as temperature and wire diameter.

Small Business Management and Entrepreneurship Slide

What type of person becomes this type of risk taker? I have always been more on the cautious side, preferring to stand back, observe, listen and analyze a situation. I’ve always admired people who are not like me, people who are more daring, or willing to throw caution to the wind. An entrepreneur tends to bite off a little more than he can chew hoping he’ll quickly learn how to chew it. What challenges did he or she face and overcome? In 1982, Mark Cuban moved to  Dallas, Texas Cuban first found work as a bartender,  then as a salesperson for Your Business Software, one of the first PC software retailers in Dallas.He was terminated less than a year later, after meeting with a client to procure new business instead of opening the store What failures did this person have?
