Question

In the activity shown in the picture energy is being converted into energy.

(A) Mechanical, sound
(B) Sound , kinetic
(C) Mechanical, kinetic
(D) Solar, potential

Answer 1

Hint :This question is based on the conversion of energy which is nothing but the transformation of energy through which there is a change in one form of energy to some other form of energy by some process. Whether the energy is transferred or transformed, the total amount of energy does not change or remains constant and this is known as the law of energy conservation.

Complete Step By Step Answer:
Before we go to the Questions we should be aware of different forms of energy
Muscular energy is the muscular movement of energy along the lines of the body, drawing muscle to bone and connecting limbs to joints as the energy moves inward to the body's core.
Mechanical energy is the energy possessed by a mechanical system due to its motion or position, however, kinetic energy is the energy of motion. But the difference is that kinetic energy is a type of energy, while mechanical energy is a form that energy takes.
 In the given figure we can see that the force is being applied by the person on the object which means that the muscular energy of that person is being converted into mechanical energy. And as the object has attained motion due to this applied energy , it is clear that the object has gained some amount of kinetic energy.
Hence, The muscular energy is converted into mechanical and kinetic energy.
Therefore, we get the C option to be the correct answer.

Note :
There are various other types of energies as well such as chemical energy, electrical energy, thermal and nuclear energy etc. All these can be converted to one form or the other but can neither be created nor be destroyed.
