Answer to Problem 36A

The conversion of the measurement $42.3\text{cm}$ into meter is $0.423\text{m}$ .

Explanation of Solution

Given info:

The measurement is $42.3\text{cm}$ .

Formula Used:

  $1\text{m}=100\text{cm}$

Calculation:

The measurement converts into meter as,

  $\begin{array}{c}42.3\text{cm}=42.3\text{cm}\times \frac{1\text{m}}{100\text{cm}}\\ =0.423\text{m}\end{array}$

(b)

To determine

Answer to Problem 36A

The conversion of the measurement $4.2\text{pm}$ into meter is $4.2\times {10}^{-12}\text{m}$ .

Explanation of Solution

Given info:

The measurement is $4.2\text{pm}$ .

Formula Used:

  $1\text{pm}={10}^{-12}\text{m}$

Calculation:

The measurement converts into meter as,

  $\begin{array}{c}4.2\text{pm}=4.2\text{pm}\times \frac{{10}^{-12}\text{m}}{1\text{pm}}\\ =4.2\times {10}^{-12}\text{m}\end{array}$

(c)

To determine

The conversion of the measurement into meter.

Answer to Problem 36A

Explanation of Solution

Given info:

The measurement is $21\text{km}$ .

Formula Used:

  $1\text{km}=1000\text{m}$

Calculation:

The measurement converts into meter as,

  $\begin{array}{c}21\text{km}=21\text{km}\times \frac{1000\text{m}}{1\text{km}}\\ =21000\text{m}\end{array}$

(d)

To determine

Answer to Problem 36A

The conversion of the measurement $214\text{μm}$ into meter is $214\times {10}^{-6}\text{m}$ .

Explanation of Solution

Given info:

The measurement is $214\text{μm}$ .

Formula Used:

  $1\text{μm}=1\times {10}^{-6}\text{m}$

Calculation:

The measurement converts into meter as,

  $\begin{array}{c}214\text{μm}=214\text{μm}\times \frac{1\times {10}^{-6}\text{m}}{1\text{μm}}\\ =214\times {10}^{-6}\text{m}\end{array}$

(f)

To determine

Answer to Problem 36A

The conversion of the measurement $57\text{nm}$ into meter is $57\times {10}^{-9}\text{m}$ .

Explanation of Solution

Given info:

The measurement is $57\text{nm}$ .

Formula Used:

  $1\text{nm}=1\times {10}^{-9}\text{m}$

Calculation:

The measurement converts into meter as,

  $\begin{array}{c}57\text{nm}=57\text{nm}\times \frac{1\times {10}^{-9}\text{m}}{1\text{nm}}\\ =57\times {10}^{-9}\text{m}\end{array}$
