Question

One kind of potential energy is elastic potential energy. This is the kind of energy present in a rubber band that is stretched. When the rubber band is released, the elastic potential energy is converted to kinetic energy. Elastic potential energy is also present in a muscle that is contracted, or tensed.

The diaphragm is a large muscle that is used to breathe. Contracting the diaphragm causes air to move into the lungs. When the diaphragm is relaxed, air moves out of the lungs as _______ is converted to kinetic energy.
A.
chemical potential energy
B.
light energy
C.
elastic potential energy
D.
heat energy

Answer 1

Answer:it c elastic

Step-by-step explanation:

Answer 2

C. Elastic potential energy

Step-by-step explanation:

Hello,

In this case, as well as the example of the rubber, when we breath, the diaphragm is contracted so the elastic potential energy is starting accumulating there, that is why we could hold the air into our lungs. Consequently, when air is released such energy in converted into kinetic energy since it was previously formed and then released.

Best regards.
