Question

a simple pendulum completes 420 oscillations in 2 minutes calculate the frequency and time period​

Answer 1

Answer:

frequency...420/2×60

420/120=42/12

7/2=3.5

time period...1/v

1/7/2=2/7

28

Answer 2

Answer:

f=2hz

time period = 0.5

Explanation:

f=oscilaation/sec

420/120

=2

time period=1/f

1/2

=0.5
