Question

The bob of a pendulum oscillates twice per second. Find its time period and frequency.​

Answer 1

Answer:

Frequency = 2 Hertz

Time period = 0.5 seconds

Explanation:

The Bob oscillates twice per second , so Frequency = 2 Hz . Time period is the reciprocal of frequency which turns out to be ½, which is 0.5 Seconds.

Answer 2

Answer:

Time Period = 0.5 seconds

Frequency = 2 Hz

Explanation:

Time period

Time taken to complete one oscillation

2 oscillation = 1 second

1 oscillation = 0.5 second

Frequency is the oscillation per second

1 second = 2 oscillations

or,

Frequency is the reciprocal of Time period

frequency = 1/time period

frequency = 1/0.5

frequency = 2 Hz
