The physical quantity which has the dimensional formula [ M^ 1 T^ -...

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

Options

  1. ASurface tension
  2. BDensity
  3. CSolar constant
  4. DCompressibility

Correct answer

C. Solar constant

Step-by-step solution

[MT−3]=[ML2T−2][L2][T]=energyarea×time\left[MT^{- 3}\right] = \dfrac{[ ML^{2}T^{- 2} ]}{\left[L^{2}\right] [ T ]} =\dfrac{energy}{area \times time}= dimensions of the solar constant.
