Question

what is the dimension of time in power​

Answer 1

Answer:

power= rate of work done

work done = mass × acceleration due to gravity × distance =mgh

power=work done ÷ time =mgh/s

unit of power = (kg×(m/s^2)×m)/s =kg m^2/s^3

Explanation:

so in term of dimensions power is M^1 L^2 T(-3)

therefore dimensions of time in power is -3

Answer 2

The dimension of time in power​  is [T]=-3.

Explanation:

The rate of doing work is called power of an object. It is given by :

$P=\dfrac{W}{t}$

W is work done

t is time taken

It can also given by :

$P=\dfrac{mgh}{t}$

Writing dimensional formula of all quantities as :

$P=\dfrac{[M][LT^{-2}][L]}{[T]}\\\\P=[ML^2T^{-3}]$

It is clear that the dimension of time in power​  is [T]=-3.
