Angular velocity of second hand of clock is 0.105 rad s^-1 and length of hand is 1.8 cm, then speed of tip of hand is {{}} A)0.189 cm s^-1 B)1 cm s^-1 C)0.189 m s^-1 D)2 m s^-1

Question

Quizplus · Accepted Answer

The speed of the tip of the hand is calculated using the formula v = ωr, where ω is the angular velocity (0.105 rad/s) and r is the radius or length of the hand (1.8 cm). Thus, v = 0.105 * 1.8 = 0.189 cm/s.
