Question

In dimensional formula of power, the modulus of exponent of time is

Answer 1

Explanation:

Power is the rate at which work is done or energy is transferred in a unit of time.

P=W/t

P- power (in watts)

W- work done or energy transferred (in joules)

t-time(in seconds)

Hence,dimensional formula for Power

Work= M1 L2 T-2

Time= T1

P=M1 L2 T-2/T1

P= M1 L2 T-3
