Question

a pendulum oscillates 20 times in 5 seconds calculate this time period and frequency​

Answer 1

Answer:

4=time period

Step-by-step explanation:

time period = no. of oscillation / time taken

4=20/5

therefore time period is 4

Answer 2

Answer:

time period is equal to number of oscillation Upon Time taken

therefore 20 upon 5 is equal to 4

number of oscillation is equal to 4
