Step-by-step explanation:
Given parameters:
Number of cycles = 10cycles
Time taken = 50s
Unknown:
Period of its rotation = ?
Frequency of its rotation = ?
Solution:
The period of rotation is the time taken time taken for a body to complete a number of rotation;
Period =
t is the time
n is the number of cycles
Period =
= 5s
The period is 5s
Now, frequency is the inverse of period;
F =
=
= 0.2Hz
