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 9.5 %.

Each climber had to eat 72 slices of bread to compensate for the increase of the gravitational potential energy of the system climbers-Earth

Explanation:

Hi

One piece of bread releases about of energy in the body, but efficiency in converting the body's chemical energy into mechanical work is 9.5 %, so .

On the other hand, we need to calculate the total work to reach the top of Mt. Everest , so

Finally, we have that
