Question

when a person pushes a large load up an inclined plane, where does the person get the energy to do this task?
electromagnetic energy
chemical energy
nuclear energy

Explanation:

The energy that a person uses to push a load comes from the food they consume. Food contains chemical - bonds. When the body metabolizes food, chemical energy stored in these bonds is released and used for physical activities like pushing a load. Electromagnetic energy is related to electric and magnetic fields and not the source of energy for human physical work. Nuclear energy is released from nuclear reactions and is not involved in human muscle - powered tasks.

Answer:

Chemical energy
