A simple pendulum completes 10 oscillations in 30 seconds frequency
Answers
Answer:
Simple Pendulum is a very small heavy metal bob suspended at a point from a firmly fixed support using a single strand thread so that it oscillates freely. The distance between the point of suspension and centre of bob is called the length of the pendulum.
One oscillation: One complete to and fro motion of the oscillating body is called one oscillation.
Frequency: It is the number of oscillations made by the body in one second.
Time Period: It is the time taken by a body to complete one oscillation.
Hence, the Frequency and Time period are calculated as follows.
Time period = Time taken by the pendulum/Number of oscillations made by the pendulum.
1020
=2s
Frequency =1/Period
21
=0.5Hz
Hence, the Time period and frequency are 2 seconds and 0.5 Hertz respectively.
