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

<em>This is an example of;</em>
B. Photoperiodism
<u>Photoperiodism is the response of an organism to seasonal changes in day length.
</u>
<u>They are classified under three groups according to the photoperiods;</u>
<u>1. Short-day plants </u>
<u>2. Long-day plants </u>
<u>3. Day-neutral plants.</u>
False because t<span>he </span>Cambrian Period<span> was when most of the major groups of animals first appear in the fossil record.</span>
The population changed the way it did because the mutation allowed the mutated animals to better survive in their environment compared to the normal species. Their size made them capable of getting food from higher branches that the normal species couldn't reach. THE ANSWER WAS ON GOOGLE
