Answer 1

Hi there,

Given,

100 cycles in 0.1 sec

i.e in unit time = 100/0.1 = 1000 cycles.

i.e frequency will be 1 kHz

Note; as earlier unit of frequency once called as cps (cycle per second)

hope it will help you.

Answer 2

GIVEN; n=100 ,t=0.1s

TO FIND; FREQUENCY=?

SOLUTION;

FREQUENCY=n/t

FREQUENCY=100/0.1

FREQUENCY=1000Hz or 1kHz
