Question

9. An object is vibrating at 50 hertz. What is its time period?
(a) 0.02 s
(b) 2 s
(c) 0.2 s
(d) 20.0 S​

Answer 1

Answer:

T = 0.02s

Step-by-step explanation:

From the definition of frequency

$v = \frac{1}{t}$

and we give v = 50 hertz

Substituting,we have

$50 = \frac{1}{t} \: or \\ t = 0.02s \: ans.$
