Question

A simple pendulum makes 2000 oscillation in 20 minutes. this time period and frequency of oscillating are respectively.​

Answer 1

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.

20

=2s

Frequency =1/Period

=0.5Hz

Hence, the Time period and frequency are 2 seconds and 0.5 Hertz respectively.

Answer 2

Answer:

A simple pendulum makes 2000 oscillation in 20 minutes. The Time period and frequency are 0.6 seconds and 1.67 Hertz respectively.

Step-by-step explanation:

• Simple pendulum is a small heavy metal bob hanging at a point from a solidly simple Pendulumured support by a single strand thread, allowing it to freely oscillate. The length of the pendulum is the distance between the point of suspension and the center of the bob.
• One oscillation is this: One oscillation is the whole to and fro motion of the oscillating body.
• The number of oscillations made by the body in one second is known as frequency.
• A body's time period is the amount of time it takes to complete one oscillation.
• As a result, the Frequency and Time Period are determined in the following manner.

Time taken by the pendulum = 20 minutes $= 20 \times 60 = 1200$second

Number of oscillations made by the pendulum =  2000 oscillation

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

$= \frac{1200}{2000}$

$=\frac{12}{20}$

$​= 0.6s$

$Frequency = \frac{1}{Period}$

$=\frac{1}{0.6}$

$= 1.67 Hz$

Hence, the Time period and frequency are 0.6 seconds and 1.67 Hertz respectively.
