QA simple pendulum condite 22 second
to complete 144 oscillation calculate
time period and fri​

Answer 1

Answer:

0.152 seconds.

Explanation:

Since from the given question we get that the pendulum completes 144 oscillation in a matter of only 22 seconds so the time period required for this oscillation will be.

We know that the time Period of the pendulum is given by the formulae of Total time taken / Number of oscillations .

So, on putting the values we will get the time period to be:-

= 22/144.

= 0.152 seconds will be the time period to complete 144 oscillation in 22 seconds.

Answer 2

a/c to question, A simple pendulum takes 22 second to complete 144 oscillation.

so, number of oscillations per second = 144/22 = 72/11 = 6.545 / sec

but we know, frequency of a simple pendulum is the number of oscillations in a second.

so, frequency of the simple pendulum = 6.545 /sec or 6.545 Hz

time period is the time taken to compete one oscillation.

so, time period is inverse of frequency.

i.e., Time period = 1/frequency

= 1/6.545

≈ 0.1527 sec

hence, time period = 0.1527 sec (approx)

hence, time period = 0.1527 sec (approx)frequency = 6.545( approx)
