Answer:
8.33 minutes
Explanation:
First let us find out how much time it takes for the light for the sun to reach the earth
Distance between Earth and Sun is 1.5×10¹¹ m
Speed of light = 3×10⁸ m/s
[tex]\text{Time taken}=\frac{1.5\times 10^{11}}{3\times 10^8}\\\Rightarrow \text{Time taken}=500\ seconds[/tex]
Converting to minutes
[tex]500\ seconds=\frac{500}{60}=8.33\ minutes[/tex]
So, it takes 8.33 minutes for the light from the sun to reach Earth.
This means that we would be receiving light for 8.33 minutes after the Sun turned off.
