Question

Owsl A pendulum oscilates no 40 times in a seconds
Find
its time period and frequency
?​

Answer 1

Answer:

Pendulum oscillates 40 times in 4 seconds find its time period and frequency

It can be given by : The reciprocal of frequency is called time period. So, Hence, time period is 0.1 seconds and frequency is 10 Hz.

Answer 2

$\huge\underline{\bf \green{ ❥ ᴀɴsᴡᴇʀ }}$

• Time Period

Time period = Time/No. of oscillations in time

→ Time period = 4/40

→ Time period = 0.1 sec

• Frequency

Frequency = 1/Time period

→ Frequency = 1/0.1

→ Frequency = 10 Hz

Hence, the time period is 0.1 sec & frequency is 10 Hz.
