Question

It takes a photon 8 minutes and 25 seconds ro reach earth. What is the distance (labeled 1 au) in meter between the sun and earth? The speed od light un a vacuum is 3e8 m/s

Answer 1

`x=0.017 AU`

Step-by-step explanation:

We can use the equation of speed in terms of distance. We know that the speed of light is constant value so we will have:

`v=(x)/(t)`

`x=v*t`

`x=3*10^(8)*8.417`

`x=2.53*10^(9)m`

Now we know that
`1 AU = 1.496*10^(11)m`

`x=0.017 AU`

I hope it helps you!
