Question

If a simple pendulum completed 30 oscillations in 60 seconds, what is its time period? *
choose any one optioon
0.5 s
1800 s
90 s
2 s

Answer 1

Answer:

2s

Explanation:

frequency = number of oscillations /time taken

= 30/60 = 1/2

time period = 1/ frequency

= 2

Answer 2

Answer is option (a) 0.5

Time period = no. of oscillations / time taken

Here , no. of oscillations = 30

time = 60 sec.

no. of oscillations / time taken = 30 / 60

0.2 answer..
