Question

a simple pendulum completes for 20 oscillations in 2 minutes calculate its frequency and time period​

Answer 1

Answer:

a simple pendulum completes for 20 oscillations in 2 minutes calculate its frequency and time period

Answer 2

Answer:

frequency=3.5m/s

time period= 1/3.5

Step-by-step explanation:

(1) Time = 2 minutes = 2*60sec =120 sec

Frequency of pendullum = total oscillation / total time taken

frequency = 420/120= 3.5 Hz

(2) Time period = 1/ frequency

= 1/ 3.5

= 0.285...
