How many slices of bread did each climber have to eat to compensate for the increase of the gravitational potential energy of the system climbers-earth? (one piece of bread releases about 1.0×106j of energy in the body.) assume that the height of mt. everest is 8850 m, the weight of a person is about 79 kg , and efficiency in converting the body's chemical energy into mechanical work is 10.5 %.
