Dimensions of physical quantities

Question

The physical quantity which has the dimensional formula $[M^{1} T^{- 3}]$ is

Moderate

A

surface tension
B

density
C

solar constant
D

compressibility

Solution

$[M T^{- 3}] = \frac{[M L^{2} T^{- 2}]}{[L^{2} [T]]}$
= energy / area $\times$ time = dimension of solar constant.
