Chapter 1, Problem 1VSC

To determine

If we wanted to show the distance between Earth and the Moon on the same scale, about how far apart would you need to place the two photos above?

Answer to Problem 1VSC

Solution:

The distance between Earth and Moon in this scale is 96cm or nearly eqaul to 1meter.

So correct option is (b).

Explanation of Solution

Given data:

Distance between Earth and the Moon on the same scale $=384000$ km Scale,

$\left(\text{1cm}/\text{4}000\text{km}\right)$

Calculation:

The distance between Earth and the Moon is 384,000 km. In the scale of the figure mentioned in the textbook, 1cm is equal to 4000 km. Thus, the Earth-Moon distance in the terms of this scale is,

$\begin{array}{l}\text{384}000\text{km}=\text{384}000\text{km}\times \frac{\text{1cm}}{\text{4}000\text{km}}\left(\because \text{1cm = 4}000\text{km}\right)\\ =\text{96cm}\end{array}$

The distance between Earth and Moon in this scale is 96cm or nearly eqaul to 1meter.

So correct option is (b).

Conclusion:

Thus, the distance between Earth and Moon in this scale is 96cm or nearly eqaul to 1meter.
