6. [-/7 Points] DETAILS OSCOLPHYS2016ACC 7.3.P.017. MY NOTES PRACTICE ANOTHER (a) How much gravitational potential energy (in ]) (relative to the ground on which it is built) is stored in an Egyptian pyramid, given its mass is about 6 x 109 kg and its center of mass is 34.0 m above the surrounding ground? (Enter a number.) (b) What is the ratio of this energy to the daily food intake of a person (1.2 x 10 J)? (Enter your answer as a ratio to the number 1. Enter a number.) 7. [-/7 Points] DETAILS OSCOLPHYS2016ACC 7.3.P.016. MY NOTES PRACTICE ANOTHER A hydroelectric power facility converts the gravitational potential energy of water behind a dam to electric energy. (For each answer, enter a number.) (a) What is the gravitational potential energy (in ]) relative to the generators of a lake of volume 32.0 km (mass = 3.20 x 1013 kg), given that the lake has an average height of 37.0 m above the generators? (b) Compare this with the energy stored in a 9-megaton fusion bomb. Elake / Ebomb =
