Physics

Which of the following statements regarding dimensions is correct?


ANSWER

The dimension of any physical quantity includes the power fundamental physical quantities.


SOLUTION
Dimensional formula includes power of fundamental quantites.
For example ; Unit of force is [$$M^1L^1T^{-2}$$]
Radian is not a fundamental physical quantity it comes under supplementary units.
Dimension of work is $$[M^1 L^2 T^{-2}]$$ whereas rate of doing work is  $$[M^1 L^2 T^{-3}]$$
