Answer:
Time taken, t = 6 minutes
Explanation:
It is given that, light from the sun reaches the earth in 8.3 minutes. We know that, the distance form the sun to earth is 1 AU.
Also, [tex]1\ AU=1.496\times 10^{11}\ m[/tex]
Time, t = 498 s
Speed of light, [tex]s=3\times 10^8\ m/s[/tex]
We have to find the time taken by the light of sun to reach Venus. The distance between the sun and the Venus is 0.723 AU.
[tex]time=\dfrac{distance}{speed}[/tex]
[tex]time=\dfrac{0.723\times 1.496\times 10^{11}}{3\times 10^8}[/tex]
[tex]t=360.53\ s[/tex]
t = 6.008 minutes
or t = 6 minutes.
Hence, the light from the sun reaches Venus in 6 minutes.
