Question

Which of the following is/are correct formula(s) for mechanical power?

A.P = W/t
B.P = Fd/t
C.P = Fv
D.both A and B
E.all of the above

Answer 1

The correct formulas for mechanical power are P = W/t, P = Fd/t, and P = Fv. Therefore, the answer to the question is E. all of the above.

Step-by-step explanation:

The correct formulas for mechanical power are:

1. P = W/t
2. P = Fd/t
3. P = Fv

Where

P

denotes power,

W

represents work,

t

stands for time,

F

is the force,

d

refers to the displacement, and

v

is the velocity. Looking into the formulas, we can see that options A (P = W/t), B (P = Fd/t), and C (P = Fv) are expressions for power. Hence, option D, which states both A and B, is correct. As C is a valid formula too, the answer is

E. all of the above
