Question

1. A simple pendulum takes 1 min to complete 45 oscillations. What is the time period of the pendulum?

Answer 1

Answer:

The answer is 1.333 seconds.

Explanation:

frequency = 45 in one minutes  => 45/60 => 0.75                      : 1 min = 60 sec :

Formula:

                  T = 1 / F

                     = 1 / 0.75

                  T = 1.333 sec
