Vedclass · Answer

(D) The solar constant $S$ is defined as the energy incident per unit area per unit time.$S = \frac{	ext{Energy}}{	ext{Area} 	imes 	ext{Time}}$The dimensional formula for energy is $[ML^2 T^{-2}]$.The dimensional formula for area is $[L^2]$.The dimensional formula for time is $[T]$.Substituting these into the formula:$[S] = \frac{[ML^2 T^{-2}]}{[L^2] 	imes [T]} = \frac{[ML^2 T^{-2}]}{[L^2 T]} = [MT^{-3}]$.Thus,the correct option is $D$.

The dimensions of the solar constant (energy falling on Earth per second per unit area) are:
