In 1980, the Environmental Protection Agency (EPA) began the Superfund Program to help clean up highly polluted areas of the environment. There are over 1300 Superfund sites across the country. Not all Superfund sites are from deliberate pollution. Some sites are old factories, where chemicals were dumped on the ground; landfills where garbage was dumped along with other poisonous waste; remote places where people secretly dumped hazardous waste because they did not know what to do with it; or old coal, iron ore, or silver mines.
According to the EPA (http://www.epa.gov/superfund/index.htm), the following groundwater contaminants were found in South Carolina Superfund sites in Greenville, Pickens, Oconee, and Anderson counties.
- Sort by city in ascending order. Examine the result: Which city appears first?
- Sort again: first by city in descending order, then by site name in descending order. Examine the results: Which site name now appears first?
- Sort again by contaminant in ascending order, then by site name in ascending order. Examine the results: Which site name appears last?

- 11.2 Boxes A and B are at rest on a conveyer belt that is initially at rest. The belt suddenly starts in an upward direction so that slipping instantly occurs between the belt and the boxes. The kinetic friction coefficients between the belt and the boxes are μk,A = 0.3 and μk,B = 0.32. Determine the initial acceleration of each box. Will the blocks stay together, or separate? 80 lb 100 lb A B 15° Hint: to see if the boxes stay together or separate, first assume they separate, and see if their resulting motion (acceleration) validates that assumption. If the their motion is not consistent with the assumption of separation, then they must stay together.arrow_forwardAn ideal gas is enclosed in a cylinder which has a movable piston. The gas is heated, resulting in an increase in temperature of the gas, and work is done by the gas on the piston so that the pressure remains constant. a) Is the work done by the gas negative, positive or zero? b) From a microscopic view, how is the internal energy of the gas molecules affected? c) Is the heat less than, greater than or equal to the work?
