Chapter 12, Problem 2PC

(a)

To determine

The period of the frequency.

Answer to Problem 2PC

The period is $0.1\text{s}$.

Explanation of Solution

Given info: The frequency is $10\text{Hz}$.

Write the expression to calculate the period.

$T=\frac{1}{f}$

Here,

$f$ is the period

$T$ is the period

Substitute $10\text{Hz}$ for $f$ in the above expression to find $T$.

$\begin{array}{c}T=\frac{1}{10\text{Hz}}\\ =0.1\text{s}\end{array}$

Conclusion:

Therefore, the period is $0.1\text{s}$.

(b)

To determine

The period of the frequency.

Answer to Problem 2PC

The period is.$5\text{s}$.

Explanation of Solution

Given info: The frequency is $0.2\text{Hz}$.

Write the expression to calculate the period.

$T=\frac{1}{f}$

Substitute $0.2\text{Hz}$ for $f$ in the above expression to find $T$.

$\begin{array}{c}T=\frac{1}{0.2\text{Hz}}\\ =5\text{s}\end{array}$

Conclusion:

Therefore, the period is $5\text{s}$.

(c)

To determine

The period of the frequency.

Answer to Problem 2PC

The period is $\frac{1}{60}\text{s}$.

Explanation of Solution

Given info: The frequency is. $60\text{Hz}$

Write the expression to calculate the period.

$T=\frac{1}{f}$

Substitute $60\text{Hz}$ for $f$ in the above expression to find $T$.

$\begin{array}{c}T=\frac{1}{60\text{Hz}}\\ =\frac{1}{60}\text{s}\end{array}$

Conclusion:

Therefore, the period is $\frac{1}{60}\text{s}$.
