- D Stefan's constant and Planck's constant
Answer & Solution
Correct Answer
(B) Frequency and velocity gradient
Step-by-step Solution
Detailed explanation
We know that, the dimension formula of given physical quantities are \([\) Force \(]=\left[\mathrm{MLT}^2\right]\) [Surface tension] \(=\left[\mathrm{ML}^0 \mathrm{~T}^{-2}\right]\) \([\) Frequency \(]=\left[\mathrm{M}^0 \mathrm{~L}^0 \mathrm{~T}^{-1}\right]\) [Velocity gradient…
