Question

9. A pendulum oscillates 50 times in 5 seconds. Calculate it's time period and frequency
(2 points)​

Answer 1

Answer:

Frequency= 10Hz

Time period = 0.1 seconds.

Step-by-step explanation:

Total number of oscillations= 50

Total time taken = 5 seconds.

Frequency =

$\frac{total \: number \: of \: oscillations}{total \: time}$

$\frac{50}{5} = 10$

Frequency = 10 Hz.

Time period =

$\frac{1}{frequency} \\ = \frac{1}{10} \\ = 0.1$

Time period = 0.1 second.
