Question

Convert 4.2 Light-Years Into Meters.

Answer 1

4.2 light-years is approximately equal to 39.8022 quadrillion meters.

Step-by-step explanation:

To convert light-years to meters, you'll need to convert light-years to kilometers and then kilometers to meters.

1 light-year = 9.461 trillion kilometers

1 kilometer = 1000 meters
So, first, let's convert 4.2 light-years to kilometers:

4.2 light-years * 9.461 trillion kilometers/light-year = X kilometers

Now, let's convert kilometers to meters:

X kilometers * 1000 meters/kilometer = Y metersCalculate X:

4.2 light-years * 9.461 trillion kilometers/light-year = 39.8022 trillion kilometers

Calculate Y:

39.8022 trillion kilometers * 1000 meters/kilometer = 39.8022 quadrillion meters

Therefore, 4.2 light-years is approximately equal to 39.8022 quadrillion meters.

Answer 2

To convert 4.2 light-years into meters, multiply 4.2 by the speed of light (approximately 299,792,458 meters per second). The answer is 3.97 x 10¹⁶ meters.

Step-by-step explanation:

A light-year is the distance that light travels in one year. To convert light-years into meters, we need to know the speed of light. The speed of light in a vacuum is approximately 299,792,458 meters per second. So, to convert 4.2 light-years into meters, we can multiply 4.2 by the speed of light:

4.2 light-years * 9.46 x 10¹⁵ meters per light-year = 3.97 x 10¹⁶ meters.
