### An oscillating system has a frequency of 20 Hz.  What is its time period

• A.

20s

• B.

1s

• C.

Explanation
The time period of an oscillating system is the time taken for one complete cycle of oscillation. In this case, the system has a frequency of 20 Hz, which means it completes 20 cycles in one second. To find the time period, we divide 1 second by the frequency. Therefore, the time period is 1/20 seconds, which is equal to 0.05 seconds.
