Angular displacement and angular velocity describe rotation, with angles measured in radians and related to time through angular speed. The connection between angular and linear quantities includes arc length, tangential speed and centripetal acceleration, so circular motion is not confused with motion at constant velocity.

- A. (∏/1800) rad/sec
- B. (∏/60) rad/sec
- C. (∏/30) rad/sec
- D. (2n) rad/sec
Explanation: The correct answer is (π/30) rad/sec. The second hand of a watch completes one full revolution (2π radians) in 60 seconds, which means its…
