Question

Choose one more correct alternative.
For work to be performed, energy must be _
A.Transferred from one place to another
B.Concentrated
C.Transformed from one type to another
D.Destroyed

Answer 1

Hint: Energy can neither be created nor be destroyed, along with this principle one or more options can be chosen from the above given options. Energy and work are related in every aspect, excess work will create more energy and more energy can give extra work.

Complete answer:
The correct answer to this question can be option C, for work to be performed, energy has to be transformed from one place to another, and it also can be option A, for work to be performed, energy has to be transferred from one place to another.
Energy can neither be created nor be destroyed, thus option D, saying that for work to be performed energy has to be destroyed, automatically becomes false.
Option B states that for work to be performed, energy has to be concentrated, this can work for specific working processes, but in general it is not true.
Option A states that for work to be performed, energy has to travel or be transferred from one place to another. This statement becomes true as we have stated that option B is false, as option B is contradictory to option A.
Option C states that for work to be performed, energy has to transform from one type to another, this is a universally true statement. As energy cannot be created, to do some work it has to transform from one type to another. This will help in processing the work that is required to be done.
Thus option A and option C are correct options.

Note:
An example of option A can be given as, to convert potential energy into kinetic energy, the object has to travel from one place to another, or to produce rotational motion through a battery, electrons need to travel in the circuit. Option C is definitely the correct answer to this question, yet option A might be true or false in certain cases.
