To store the energy produced in 1.0 hour by a 190 electric power plant, how many cubic meters of water will have to be pumped from the lower to the upper reservoir? Assume the upper reservoir is 340 above the lower one, and we can neglect the small change in depths of each. Water has a mass of for every 1.0
