Question

A simple pendulum takes 20s to complete 72 oscillations. What is the time period of this pendulum​

Answer 1

Step-by-step explanation:

Time period is defined time taken to complete one oscillation.

Here, time taken to complete one oscillation= 20/72= 0.27 sec

Answer 2

Answer: the formula for time period is t/sec so ....20/72

20/72 is 10/36 when we cancel by 2...10/36 is 5/18 whem u cancel by 2 so in fraction it is 5/18 or in decimal it is 0.27777777777
