Answer:
Explanation:
This figure given is the frequency; 2 times per second represents frequency.
What is frequency?
- It is the number of times per seconds something goes past or around another.
it is expressed as:
Frequency = [tex]\frac{n}{t}[/tex]
where n is the number of turns
t is the time taken
Therefore, the Barber spinned him 2 times in 1 second.
The period is the inverse of frequency. It is the time taken for a body to go through a point;
Period = [tex]\frac{t}{n } = \frac{1}{f}[/tex] = [tex]\frac{1}{2}[/tex]s
