Question

In a ceiling fan, electrical energy, N, is transferred to another form, M. Energy transfers are never 100% efficient. Some of the energy is "wasted" as heat. To what form is the electrical energy (N) transferred (M) to allow the ceiling fan to function? A) light energy B) kinetic energy C) chemical energy D) potential energy

Answer 1

In a ceiling fan, electrical energy, N, is transferred to another form, M. Energy transfers are never 100% efficient. Some of the energy is "wasted" as heat. To what form is the electrical energy (N) transferred (M) to allow the ceiling fan to function? The answer B. Kinetic Energy

Explanation:Electrical energy (N) is transferred to: kinetic energy (M)

Electrical energy causes the fan blades to turn. The energy of motion is kinetic energy.

Answer 2

Answer: B) kinetic energy

Explanation: Light energy is the form of radiant energy which travels through space.

Kinetic energy is the energy possessed by an object by virtue of its motion.

Chemical energy is stored in the bonds of the molecules.

Potential energy is the energy possessed by an object by virtue of its position.

According to the law of conservation of energy, energy can neither be created nor be destroyed. It can transform from one form to another.

Thus when electrical energy is put into ceiling fan , it converts it into kinetic energy and results in the movement of blades of the fan which then results into cooling of air.
