Because of its metabolic processes, your body continually emits thermal energy. suppose that the air in your bedroom absorbs all of this thermal energy during the time you sleep at night (8.0 hours). assume your metabolic rate to be p = 100 j/s.

a and c

c is 100% but i am confused in a

answer would be letter choice (a),   a ball resting on a shelf. would be another example of potential energy   >   stored energy > not moving.

a ball spinning on a finger   >   kinetic energy > moving energy

a ball rolling on the ground   >   kinetic energy   > moving energy

a   ball flying through the air   > kinetic energy   >   moving energy

the motion of a pendulum is a classic example of mechanical energy conservation. a pendulum consists of a mass (known as a bob ) attached by a string to a pivot point. as the pendulum moves it sweeps out a circular arc, moving back and forth in a periodic fashion.
