Question

A pendulum oscillates 40 times in 4 seconds. find its time period and frequency ​

Answer 1

Answer:

Time period = (4/40) =0.1 sec

Frequency = (no. of oscillations/time taken ) = (40/4)=10 hz

Answer 2

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

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.
