Question

light from the sun reaches the earth in 8.3 minutes . In how many minutes does the light from the sun reach venus

Answer 1

6 minutes. or in seconds it would be 0723 360.0 seconds

Answer 2

Time taken, t = 6 minutes

Step-by-step 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,
`1\ AU=1.496* 10^(11)\ m`

Time, t = 498 s

Speed of light,
`s=3* 10^8\ m/s`

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.

`time=(distance)/(speed)`

`time=(0.723* 1.496* 10^(11))/(3* 10^8)`

`t=360.53\ s`

t = 6.008 minutes

or t = 6 minutes.

Hence, the light from the sun reaches Venus in 6 minutes.
