Question

The angular speed of the minute hand of the clock in degrees per second is:

• A. $1.0$
• B. $0.1$
• C. $0.001$
• D. none of these

Answer 1

The correct option is B $0.1$

The minute hand, in one hour ($=3600s$) completes a full ${360}^{\circ }$ rotation.

So its angular speed is given by:
$\omega =\frac{\Delta \theta }{\Delta t}=\frac{{360}^{\circ }}{3600s}={0.1}^{\circ }{s}^{-1}$
