Answer:
A. Energy cannot be created, but it can be destroyed.
Explanation:
We are informed from the question about Dale, who is learning about the Law of Conservation of Energy and he wants to know what it means. We are told that He knows that conserving natural resources means that you do not waste them. For example, he makes sure to turn off the lights when he leaves a room.
What is meant by the conservation of energy is "Energy cannot be created, but it can be destroyed". In physics, law of Conservation of Energy states that energy cannot be created or destroyed, but can be transformed from one form to another. This implies that energy can be transferred, one of the instance is in the "swinging of pendulum in upward direction" where kinetic is converted to potential energy
The forms of energy are Chemical, solar, electrical, thermal radiant sound.
However there are two major types of energy which are Kinetic and potential energy.
Please be helpful? idk to this question
