Metaphase is the correct answer
Disrupts the nitrogen cycle by contaminating the groundwater and making it more difficult for the plants to absorb the nitrogen and causes the phosphorus cycle to accelerate, resulting in an excess of phosphorus in water and soil.
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
