Calculate the angular speed of the second's hand of clock, assuming that it moves with a uniform angular speed. If the length of the second's hand is $2cm$.

Q. If the length of second's hand of a clock is $10cm$, the speed of its tip (in $cm{s}^{-1}$) is nearly

Q. The second's hand of a watch is $2cm$ long. The speed of the tip of this hand is:

Q.

(a) What is meant by uniform circular motion? Give two examples of uniform circular motion.

(b) The tip of seconds' hand of a clock takes 60 seconds to move once on the circular dial of the clock. If the radius of the dial of the clock is 10.5 cm, calculate the speed of the tip of the second's hand of the clock. ($Given\pi =\frac{22}{7}$).

Q. The angular speed of second's clock is $\frac{\pi }{x}rad/s$. Find the value of $x/10$.

Q. The second's hand of a watch has length 6 cm. Speed of end point and magnitude of different velocities at two perpendicular positions will be
