Answer & Solution
Correct Answer
(B) Surface tension and impulse
Step-by-step Solution
Detailed explanation
[Angular momentum \(]=\mathrm{ML}^2 \mathrm{~T}^{-1}\) [Planck's Constant] \(=\mathrm{ML}^2 \mathrm{~T}^{-1}\) [Torque] \(=\mathrm{ML}^2 \mathrm{~T}^{-2}\) [Energy] \(=\mathrm{ML}^2 \mathrm{~T}^{-2}\) [Surface tension] \(=\mathrm{MT}^{-2}\) [Impulse]= MLT \(^{-1}\) [Pressure…
