Q. Solar constant is defined as energy received by earth per $cm^{2}$ per minute. The dimensions of solar constant are
A) $\lbrack ML^{2}T^{- 3}\rbrack$
B) $\lbrack M^{2}L^{0}T^{- 1}\rbrack$
C) $\lbrack ML^{0}T^{- 3}\rbrack$
D) $\lbrack MLT^{- 2}\rbrack$
Explanation
Solar constant $= \frac{energy}{cm^{2}\min}$ $\therefore\ \ \$The dimensions of solar constant $= \frac{\left\lbrack ML^{2}T^{- 2} \right\rbrack}{\left\lbrack L^{2}T \right\rbrack} = \lbrack ML^{0}T^{- 3}\rbrack$
