Question

1 light-year = 9.46 × 10 to the power 15 right?

Answer 1

Answer:

A light-year is the distance light travels in a year.

The speed of light is 299,792,458 meters per second.

There are 31,557,600 seconds in a year. (60 second per minute * 60 minutes per hour * 24 hours per day * 365.25 days per year). Multiplying speed times time gives you distance. So, 299,792,458 * 31,557,600 gives you 9,460,730,472,580,800 or, simplified and rounded, 9.46 * 10^15

Answer 2

1 light year = 9.46×10^15 metres
