A hydroelectric power facility converts the gravitational potential energy of water behind a dam to electric energy. What is the gravitational potential energy relative to the generators of a lake of volume 50.0 kmº (mass = 5.00 x 1013 kg), given that the lake has an average height of
40.0 m above the generators?
