Chapter 9, Problem 106E

Interpretation Introduction

Interpretation:

The distance between the star, Alpha Centauri and Earth in kilometers is to be calculated when the distance between Alpha Centauri and earth is $4.3\text{ light years}$.

Concept Introduction:

A light year is defined as the distance traveled by the light in one year $\left(365\text{ days}\right)$. The given distance between Alpha Centauri and Earth is $4.3\text{ light years}$. In order to calculate the distance between Alpha Centauri and Earth in kilometers first, convert the speed of light in $\text{km/year}$. Followed by this, multiply the speed of light in $\text{km/year}$ with $4.3\text{ light years}$.
