Joule second is the unit of
- A Angular momentum
- B Linear momentum
- C Power
- D Energy
Answer & Solution
Correct Answer
(A) Angular momentum
Step-by-step Solution
Detailed explanation
The unit of energy is Joule (J) and the unit of time is second (s). The unit Joule second (J s) corresponds to the product of energy and time. From the relation \(E = h \nu\), where \(E\) is energy and \(\nu\) is frequency, the unit of Planck constant \(h\) is…
