The miners trapped in the San Jose copper mine in Chile are 700 meters below ground. Calculate the work needed to raise one 70 kg miner to the earth's surface, assuming the acceleration due to gravity is constant and 9.802 m/s^2. If the density of the atmosphere is 1.17 g/L, what is the excess pressure in bars over standard atmospheric pressure at a depth of 700 m?
