Impacts Of Rock Mining Industries - 1808 Words

Impacts of Rock-Mining Industries Industrial development and population growth have created a surge in global demand for energy. According to †Annual Emissions of Carbon Dioxide from the Combustion of Fossil Fuels and Production of Cement by Region: 1850-2006,† human population has been growing carbon emission. Moreover, the tension in the Middle East and the sharp rise in oil prices since the 1990’s had Western countries like the US scrambling to secure alternative energy sources. While solar and wind energy is flourishing, energy industries have pursued more aggressive means of tapping the earth’s resources. Continued mining, drilling, and especially hydraulic fracturing have been a â€Å"game changer† for the US. Although industrialized energy development is making great strides in harnessing the earth’s energy resources, it is also threatening the natural environment and the quality of life in many communities. â€Å"Fracking† refers to hydraulic or hydro fracturin g of rock formations to stimulate and extract natural gas and oil. The process involves drilling down through sedimentary rocks for thousands of feet, then sideways for miles, pumping millions of gallons of water, sand, and chemicals at high pressure to open fractures in the rocks, allowing gas and oil to flow. This relatively new technology is also being used for resource exploration by geothermal developers. Prior to fracking, it was too expensive to exploit â€Å"shale gas†, but it is now being viewed as a way forShow MoreRelatedHealth And Social Harms Of Coal Mining1157 Words   |  5 PagesEFFECTS OF MINING IN AUSTRALIA Student Name: Ganesh Lakshmi Teacher Name: Shanes Bennett Hilda â€Æ' Contents Page No. Introduction 3 Health and social harms of coal mining 3 Some serious threats by mining minerals 4 Deforestation 5 Solutions to control mining problems 6 ReferencesRead MoreTaking a look at Mine Waste824 Words   |  3 Pagesopen-pit mining, the overburden material was removed to gain access to the ore and placed in massive rock piles.

Physics Lab Report Centripetal Force Essay Example For Students

Physics Lab Report Centripetal Force Essay Centripetal force F is the net force causing the centripetal acceleration of an object performing uniform circular motion. Its magnitude is given by the equation: F = Mrs. When an object is whirled in horizontal circular motion in mid-air with a piece of string (as shown in figure 1 above), the centripetal force on the object is provided by the horizontal component of tension in the string: 2 =>2 (since r = L) Procedure 1 A triple beam balance is used to find the mass of the rubber bung, the screw nuts and the wire hook respectively. The total weight of the screw nuts and the wire hook provided the tension T in the nylon thread. The centripetal force apparatus is set up (Figure 2). The paper marker is used to set the length L of the nylon string between the rubber bung and the glass tube to 0. 2 m. 3 Hold the glass tube vertically and whirl the rubber bung around in a horizontal circle. Increase the speed of the rubber bung gradually until the paper marker is Just below the lower end of the glass tube (Figure 3). 4 The time of 50 revolutions of the rubber bung is measured and record the results. Calculate the angular velocity w of the rubber bung and the tension T in the nylon string. 5 The steps 1, 2 and 3 is repeated for several times with different lengths L (0. , 0. Mm and 0. Mm) of the nylon string. The results are recorded and the mean tension T in the nylon string is calculated. 6 Compare the mean tension (2) found in circular motion and the weight of screw nuts and wire hook (MGM). Explain their difference (if any) briefly. It the two values are close to each other, it could be concluded that the equ ation for centripetal force is 7 Find out the possible sources of error in this experiment. 8 Suggest improvements for the accuracy of the experiments. Precautions 0 In step 2, remove all breakable stuff and clear the area before whirling Wear safety goggles to perform this experiment Thus, the motion of the circulation may be affected and the measurement of angular velocity might not be accurate. 2. Secondly, constant speed or constant angular velocity of the rubber bung may not be maintained during the whirling. Thus, the measurement of angular velocity might not be accurate. 3. The radius of the circular motion and thus the length of nylon string L cannot be kept constant throughout the circular motion because there may be a variance of the force applied to keep the paper marker on the level of glass tube. Thus, the string and paper marker may move up and down and the accuracy of the tension T may be affected. The stopwatch is controlled by human hands. Thus, the reaction time of human brain (around 0. As) may lead to inaccuracy and affect the measurement of time taken and hence the accuracy of angular velocity is affected. 5. There may be miscounting in the number of circulations, because the time for 50 revolutions is quite long and students may be distracted . The accuracy of the experimental results can be improved by the following suggestions: 1. The experiment was carried out with the range of L 0. Mm, 0. Mm, 0. Mm, 0. Mm. Further experiments can be carried out beyond this range to increase the accuracy.
