Answer 1

Answer:

☆Answer☆

the pendulum oscillates 80 times in 1 second.

the pendulum oscillates 80 times in 1 second.so time taken to oscillate once= 1/50 secs =0.02 secs

the pendulum oscillates 80 times in 1 second.so time taken to oscillate once= 1/50 secs =0.02 secsso time period of the pendulum is 0.02 secs.

the pendulum oscillates 80 times in 1 second.so time taken to oscillate once= 1/50 secs =0.02 secsso time period of the pendulum is 0.02 secs.frequency = 1/time period= 1/0.02 Hz = 50Hz
