Question

4. If a simple pendulum makes 20 oscillations in 4 seconds, what is its frequency​

Answer 1

Answer:

5

Explanation:

frequency = no. of ossilation over time

so; 20/4=5

Answer 2

Answer:

f=20/4 = 5 s^(-1)

Explanation:

frequency is just no. per unit time,so a/c to question there is 20 oscillations executed in 4 seconds ,so the frequency (no. of oscillations per second) is 20/4=5 Hz or Cycle per second
