Answer:

a = 0.1 s b. 10 s

Step-by-step explanation:

Given that,

The frequency in circular motion, f = 10 Hz

(a) Let T is the period of itsrotation. We know that,

T = 1/f

So,

T = 1/10

= 0.1 s

(b) Frequency is number of rotations per unit time. So,


t=(n)/(f)\\\\t=(100)/(10)\\\\t=10\ s

Hence, this is the required solution.
