Question

calculate number of oscillation if pendulum frequency is 40 hertz for the 3 second​

Answer 1

Answer:

Number of oscillation is 120

Explanation:

Frequency = no of oscillations ÷ time

$f=\frac{n}{t} \\n=f \times t$

here n is the number of oscillations, f = 40 Hz is the frequency, t= 3s  is time taken.

Number of oscillation is $40 \times 3 =120$

Number of oscillation is 120
