a simple pendulum makes 2000 oscillation in 20 minutes. the time period and frequency of oscillation are respectively
Answers
Answer:
the answer is 100 minutes and 1000 hertz
Explanation:
A simple pendulum makes 2000 oscillations in 20 minutes. What is the time period and frequency of its oscillation?
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.
10
20
=100
Frequency =1/Period
2
1
=0.5Hz
Hence, the Time period and frequency are 2 seconds and 1000 Hertz respectively
Answer:
For a simple pendulum, the time period and frequency of oscillation are 0.01 sec and 100 Hz respectively.
Explanation:
Given, the number of the oscillations of the simple pendulum = 2000
The time taken for 2000 oscillations = 20 min = 20 × 60 = 1200 sec
The frequency of the oscillation can be calculated from the ratio of the number of oscillation divided by time.
Frequency of oscillation = Number of oscillations/time
Frequency
The time period of oscillation is inverse of the frequency of oscillation for a simple pendulum.
Time period of oscillation
Therefore, the time period and frequency of oscillation are 0.01 sec and 100Hz respectively.
