Question

. If a simple pendulum has time period of 6 sec in 1 minute, then find the 
    number of oscillations
    (a)   1/6
  (b)    5
    (c)    10
    (d)    6​

Answer 1

Answer:

ANSWER

Given

Number of Oscillations, N=40

Time t=1min

Frequency f=

t

N

=

60

40

=0.667Hz

Time period,T=

f

1

=1.5sec

Hence, frequency is 0.667Hz and time period is 1.5sec

Answer 2

Answer:

10 Oscillation of simple pendulum
