Question

An object completes 10 cycles in 50s.

Answer 1

Answer:

.

Explanation:

Answer 2

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  = $\frac{t}{n}$  

t is the time

n is the number of cycles

 Period  = $\frac{50}{10}$  = 5s

The period is 5s

Now, frequency is the inverse of period;

   F = $\frac{1}{period}$  = $\frac{1}{5}$   = 0.2Hz
