Question
If a pendulum takes 2 s to complete one oscillation, then how much time will it take to complete 15 oscillations?
- 30 s
- 45 s
- 10 s
- 7.5 s
Hint:
Oscillation is defined as the process of repeating variations of any quantity or measure about its equilibrium value in time.
The correct answer is: 30 s
For one oscillation it takes 2 s
then for 15 osicalltion it will take
