Answer:
20[tex]s^{-1}[/tex]
Solution:
We Know that frequenency is defined as the number of times something happens within a specific period of time.
Frequency is related with time by following formula
Frequency=[tex]\frac{1}{T}[/tex]
Here T is time period=.05
Therefore,
Frequency=[tex]\frac{1}{.05}[/tex]
Frequency=20[tex]s^{-1}[/tex]
