Question

An object completes 300 oscillations in 60 seconds . What will be it's time period and frequency ? *

0.2 sec , 50 Hz
2 sec , 50 Hz
0.2 sec , 5 Hz
2 sec , 2 Hz​

Answer 1

Answer ::

The frequency and the time period of the object is 5Hz and 0.2 seconds.

[ Option c. ] is the correct answer.

Step-by-step explanation ::

To Find :-

• Time period and the frequency of an object

Solution :-

Given that,

• Number of oscillation an object completes in 60 seconds = 300

Therefore,

• Number of oscillation = 300
• Time = 60 seconds

ACCORDING THE QUESTION,

The frequency of the object is,

As we know that,

$\dag \boxed{\sf{Frequency = \dfrac{Number \: of \: oscillation}{Time}}}$

➠ Frequency = 300 / 60

➠ 30 / 6

➠ 5 Hz

The frequency of the object is 5Hz.

Now, Time period is,

As we know that,

$\dag \boxed{\sf{Time \: period = \dfrac{1}{Frequency}}}$

➠ Time period = 1 / 5

➠ 0.2

The time period of the object is 0.2 seconds.
