Question

a pendulum oscillates 50 times in 12 seconds find its frequency and time period​

Answer 1

Answer:

MARK ME AS BRAINLIST

Explanation:

SOLUTION : ⇒the pendulum oscillates 50 times in 6 secs. so time period of the pendulum is 0.12 secs. frequency = 1/time period= 1/0.12 Hz = 8.33 Hz [Answer]

Answer 2

Answer:

the pendulum oscillates 50 times in 12 secs.

so time taken to oscillate once= 6/50 secs = 0.12  secs

so time period of the pendulum is 0.24 secs.

frequency = 1/time period= 1/0.24 Hz = 4.16  [Answer].
