1.Units, Dimensions and Measurement
medium
The dimensions of solar constant (energy falling on earth per second per unit area) are
A$\left[ M ^0 L ^0 T ^0\right]$
B$\left[ MLT ^{-2}\right]$
C$\left[ ML ^2 T ^{-2}\right]$
D$\left[ MT ^{-3}\right]$
Solution
(D)
Solar constant $[S]=\frac{\text { Energy }}{\text { Area } \times \text { Time }}=\frac{M^2 T^{-2}}{L^2 T} \Rightarrow\left[M T T^{-3}\right]$
Solar constant $[S]=\frac{\text { Energy }}{\text { Area } \times \text { Time }}=\frac{M^2 T^{-2}}{L^2 T} \Rightarrow\left[M T T^{-3}\right]$
