Answer:
It takes 500 seconds
Step-by-step explanation:
Light travels at a rate of 3.0 × [tex]10^{8}[/tex] meters per second.
Distance of earth from the sun is 1.5 × [tex]10^{11}[/tex] meters.
We have to calculate the time it takes to reach the earth from sun
Since speed = [tex]\frac{Distance}{Time}[/tex]
3.0 × [tex]10^{8}[/tex] = [tex]\frac{1.5\times 10^{11}}{T}[/tex]
T = [tex]\frac{1.5\times 10^{11}}{3\times 10^{8}}[/tex]
= 0.5 × [tex]10^{11}[/tex] × [tex]10^{-8}[/tex]
= 0.5 × [tex]10^{11-8}[/tex]
= 0.5 × [tex]10^{3}[/tex]
= 500 seconds.
It takes 500 seconds for light to travel from the sun to the earth.
