Answer 2

Change of energy from on form to another

Explanation:

We are familiar with Law of conservation of energy .

According to it , Energy can neither be created nor be destroyed but can be converted from one form to another ,

In the given data the correct energy conversions are :

.B) An athlete exercising is an example of mechanical energy being converted to heat energy.

D) The emission of light from the sun is an example of light energy being converted to heat energy.

E)An electrical fan which is running is an example of electrical energy being converted to mechanical energy.

When water from a dam is used to generate electricity and energy conversion is :

A) potential energy is converted to electrical energy.
