Question

A unit used for measuring very large distances is called a light year. It is the
distance covered by light in one year. Express light year in metres. Take
speed of light as 3 × 108
m s–1

Answer 1

Answer:

seconds in one year= 31536000

so speed of light = 3*10^8

so distance in metre for light year would be

=>3*10^8*31536*10^3

=>94608*10^11 metre
