Question

a simple pendulum completes 50 oscillations in one minutes find its frequency and time period​

Answer 1

Answer:

No. of oscillations = N= 50

time taken for oscillations= t = 1 min or 60 sec

frequency, f=N/t

=50/60

= 5/6 or 0.833 Hz or 0.833 sec^-1

Time period,T= 1/f

= 1/0.833

= 1.2 sec

Answer 2

$\huge\star\mathfrak\red{{Hey Mate...!!}}$

(1) Frequency = oscillation/Time

Frequency = 50/60

Frequency = 5/6Hz

(2) Time period = Time/Oscillation

Time Period = 60/50

Time Period = 6/5sec
