If a flare occurs on the Sun 4 astronomical units away how much time would pass before a robot at that distance see the light fl
neonofarm [45]

The time that would elapse before a robot at a distance see the light flash is : 2000 secs

<h3 /><h3>Analysis of the solution </h3>

<u>Given data :</u>

Distance = 4 AU

Time for light to reach the earth = 8 mins 20 seconds

speed of light ( c ) = 299,792,458 m / s

To resolve this we will apply the equation below

Time = Distance / Speed ------ ( 1 )

where :  Distance= 4 AU, speed = c

Therefore :

Time = 4 AU / c

AU / c = ( 8 * 60 + 20)

Hence the time that would elapse before a robot at a distance see the light flash will be  

Time = 4 ( 8*60 + 20) = 2000 secs
