Question

An oscillating object completes 100 oscillations in 20 seconds. Its frequency is.

Answer 1

⭐HEY THERE!!

**********************
=) Frequency : Number of complete oscillations in one second is known as frequency.

***********************
NUMERICAL:

=> In 20 sec number of oscillations = 100

=>in 1 sec number of oscillations = 100/20

= 5

so , frequency = 5 hertz(Hz)
