Question

A pendulum takes 64 second to complete 25 oscillations what is the time period of the pendulum

Answer 1

Answer:

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

Answer 2

Answer:

2.56 sec

64÷24

as 64 osc in 20 sec
