Question

calculate the time period of the pendulum , which took 42 seconds to complete 24 oscillations​

Answer 1

Answer:

Time period= 2.1 seconds

Explanation:

No. of oscillations completed by the pendulum= 42

Time taken to complete 42 oscillation= 20 seconds

Time period= No. of oscillations completed/Time taken

Time period= 42/20

= 21/10 (cancelled by 2)

= 2.1

Time period= 2.1 seconds
