Question

write the dimensional formula for power

Answer 1

Power is defined as rate of doing work.
Power = work / time
DIMENSIONAL FORMULA of work= M1L2T-2
DIMENSIONAL FORMULA of Time is T
Power=M1L2T-2/T
= M1L2T-3

Answer 2

Answer:

M^1L^2T^-3

Explanation:

power=work/time

dimensions=>

            1.work=M^1L^2L^-2

            2.time=T^1

therefore,power=M^1L^2L^-2/T^1

                         =M^1L^2T^-3
