Answer:
Periods are 60 seconds, 60 minutes and 12 hours frequency are their reciprocal.
Explanation:
For second hand, period = 1 min = 3660 s; frequency = 0.0166
For minute hand, period = 1 hr = 3600 s; frequency = 2.77}
For hour hand, period = 12 hrs = 4300 s; frequency = 2.3}
Since the mass is 5 grams the acceleration is: 4000 m/s^2
But if the mass is 5 Kilograms the acceleration is: 4 m/s^2
