Question

A SIMPLE PENDULUM MAKES 20 OSCILLATIONS IN 40 SECONDS. WHAT IS THE TIME PERIOD AND FREQUENCY OF ITS OSCILLATIONS. ANYONE PLZ ANSWER MY QUESTION FAST PLZ

Answer 1

Answer:

time period = 20/40

= 1/2 s

frequency= 40/20

= 2/s

time period is the time taken to complete one oscillation whereas the frequency is the number of oscillation per second..

Answer 2

Answer:

Time Period = 2 seconds

Frequency = 0.5 Hz

Explanation:

1st Know its Definition :

Time Period : It is the time taken by a body to complete one oscillation.

Time period = Time taken by the pendulum/Number of oscillations made by the pendulum.

= 40/20

= 2 seconds

Frequency :  It is the number of oscillations made by the body in one second.

Frequency = (1/Time period)

                  = (1/2)

                  = 0.5 Hz

Therefore.

Time Period = 2 seconds

Frequency = 0.5 Hz

Hope it helps!
