Question

a body makes 1800 oscillations in 1 minute find out its frequency and time period ​

Answer 1

Answer:

f = 30 Hz, T= 0.03 (approx.)

Explanation:

osc = 1800

t = 1min = 60 sec

frequency = oscillations/time

f = 1800/60

f = 30 Hz

Time period = 1/f

Time period = 1/30  = 0.03 (approx.)

Answer 2

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
