Question

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

Answer 1

Answer:

A pendulum oscillates 40 times in 4 seconds. Find its time period and frequency. Frequency of oscillations is the number of oscillations of a vibrating object per second. Therefore frequency is = 40 vibrations /4 seconds= 10 Hertz.

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.
