bros and sisters pls tell me answers​

Answer 1

Answer:

1. Frequency = Number of vibrations in one second.

So, if frequency is 100 Hz,

Hence, it had completed 100 vibrations in a minute.

Answer 2

Frequency is the rate at which current changes direction per second. It is measured in hertz (Hz), an international unit of measure where 1 hertz is equal to 1 cycle per second. Hertz (Hz) = One hertz is equal to one cycle per second. Cycle = One complete wave of alternating current or voltage.
