Question

After getting a haircut, Joey’s barber spins him around in his barber’s chair 2 times per second. Is period or frequency given? ________________ What is the period? ______ What is the frequency? __________ (if you can please answer the other questions, would really appreciate it)

Answer 1

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  = $\frac{n}{t}$

                  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  = $\frac{t}{n } = \frac{1}{f}$    = $\frac{1}{2}$s
