Which of the following quantity represents the dimensions of momentum?
- A Impulse
- B Pressure
- C Viscosity
- D Power
Answer & Solution
Correct Answer
(A) Impulse
Step-by-step Solution
Detailed explanation
The dimension of momentum \(p\) is given by \(p = mv\), where \(m\) is mass (\(M\)) and \(v\) is velocity (\(LT^{-1}\)). Thus, the dimensions of momentum are \([MLT^{-1}]\). Impulse \(J\) is defined as the change in momentum, \(J = \Delta p = F \Delta t\). The dimensions of…
