The physical quantity which has the dimensional formula M1T−3M ^ { 1 } T ^ { - 3 } is

A

Surface tension

B

Solar constant

C

Density

D

Compressibility

Answer

Solar constant

Explanation

Solution

Solar constant is energy received per unit area per unit time i.e. [ML2T−2][L2][T]=[M1T−3]\frac { \left[ M L ^ { 2 } T ^ { - 2 } \right] } { \left[ L ^ { 2 } \right] [ T ] } = \left[ M ^ { 1 } T ^ { - 3 } \right]
