Question

an object vibrates 500 times in 50 seconds. what is its frequency and time period​

Answer 1

Answer:

Frequency = 500 vibrations/second. = (1/500) = 0.002 sec.

Answer 2

Answer :-

• Frequency = 10 Hz
• Time period = 0.1 seconds.

Step-by-step explanation:

To Find :-

• The frequency
• The time period.

★ Solution

Given that,

• An object vibrates 500 times in 50 seconds.

∴ The number of oscillations in 50 seconds is 500 times.

According the question,

• The frequency :-

We know,

Frequency (f) = Number of oscillations/Time (T)

⟶ Number of oscillations/Time

⟶ 500/50

⟶ 50/5

⟶ 10 Hz

Hence, The frequency is 10Hz.

Now,

• The time period :-

We know,

Time period (T) = 1/Frequency (f)

⟶ 1/Frequency

⟶ 1/10

⟶ 0.1 secs

Hence, The time period is 0.1secs.

Formulas used :-

• Frequency = No. of oscillations/Time
• Time period = 1/Frequency.
