Question

1.A simple pendulum takes 80 s to complete 20 oscillations. What is the time-

period of the pendulum?

​

Answer 1

Answer:

here is your answer

Explanation:

Number of oscillations completed by the pendulum = 20

Time taken to complete 20 oscillations = 32 seconds

Time period of the pendulum is defined as the time taken by the pendulum to complete one oscillation.

Hence,

Time period = \frac{32}{20}

20

32

Time period = 1.6 seconds

Hence, the time period of the pendulum is 1.6 seconds
