Vedclass · Answer

(D) Intensity $(I)$ is defined as the power $(P)$ transmitted per unit area $(A)$.$I = \frac{P}{A}$Power is energy $(E)$ per unit time $(t)$,so $P = \frac{E}{t}$.Dimensional formula of energy $[E] = [M^1L^2T^{-2}]$.Dimensional formula of time $[t] = [T^1]$.Dimensional formula of area $[A] = [L^2]$.Therefore,the dimensional formula of intensity is:$[I] = \frac{[M^1L^2T^{-2}]}{[T^1] \cdot [L^2]}$$[I] = [M^1L^0T^{-3}]$Thus,the correct option is $D$.
