Answer 1

Answer:

Mark as brainlist..!!

Explanation:

Your answer

POWER = work done by time taken

formula =

work done / time taken

so dimensional formula will be M1L2T-2 / T

so M1L2T-3 will be dimensional formula of power.

VELOCITY = M0L1T-1

ENERGY = M1L2T-2

DENSITY = Mass by volume

formula = M1L-3T0

FREQUENCY = 1 BY TIME

FORMULA WILL BE M0L0T-1

REFRACTIVE INDEX = It is the ratio of physical quantity so it will be dimension less

Formula = M0L0T0
