Question

A pendulum oscillates 100 times in 5 seconds. Find the time period and frequency.

Answer 1

Answer:

Time period = t\n

t =5 sec

n =100

thus, T = t\n =5\100

= 1\20 = 0.5 sec = Timeperion

Explanation:

T = t\n

Answer 2

Given - Number of oscillations and time

Find - Time period and frequency

Solution - Time period and frequency are 0.05 seconds and 20 Hertz.

The frequency refers to the number of oscillations taking place per second.

So, frequency = 100/5

Frequency = 20 Hertz

Time period of the pendulum will be reciprocal of its frequency.

So, time period = 1/20

Time period = 0.05 second

Thus, time period and frequency are 0.05 seconds and 20 Hertz.
