Question

An object is vibrating at 20 hertz. What is its time period? 

5 s

0.05 s

0.5 s

50.0 s

​

Answer 1

Answer:

• Option (2) 0.05 s is the required answer.

Explanation:

Given:-

• Frequency ,f = 20 Hz

To Find:-

• Time Period,T

Solution:-

As we know that the relationship between Frequency & Time period .

• T = 1/f

Time Period is inversely proportional to Frequency .It means that If we increase time period then the frequency will get decrease & vice - versa.

where,

• T denote Time period
• f denote frequency

Substitute the value we get

→ T = 1/20

→ T = 0.05 s

• Hence, the time period of the vibrating object is 0.05 second

Option (2) 0.05 is the required answer

Answer 2

Answer:

$\huge\underline\mathfrak\blue{question}$

An object is vibrating at 20 Hertz. what is the time period?

$\huge\underline\mathfrak\reda{Answer}$

$from \: the \: definition \: of \: frequency = \frac{1}{t}$

$and \: we \: gaven \: v = 20hertz$

$subtracting \: we \: have \: 20 = \frac{1}{t}$

$= \frac{1}{20} = 0.05s$
