A pendulum is observed to complete 23 full cycles in 58 seconds. Determine the period and the frequency of the pendulum.
1

Frequency=0.39Hz

Explanation:

A pendulum completes 23 full cycles in 58 seconds

A pendulum completes 1 full cycle in 58/23=2.52 seconds

Time taken(t)=2.52 seconds

Now,

Frequency=1/time taken

Frequency=1/2.25

Frequency=0.39Hz

explanation: magnetic pole, region at each end of a magnet where the external magnetic field is strongest. the south-seeking pole, or any pole similar to it, is called a south magnetic pole. unlike poles of different magnets attract each other; like poles repel each other.
