one light year is defined as the distance travelled by light in 1 year.The speed of light is 3×10^8m/s .The same in meters is...​

Answer 1

Explanation:

The speed of light =300,000,000m/s

Length of earth year 365days=365×24=365×24×60

minutes = 365×24×60×60 second 3.15×10^7 seconds

Now speed distance/time...so distance...=speed ×time

so: one light year 3.00× 10^8×3.15×10^7

1 light year=9.46×10^15 m
