Answer:
Total time= 2.56 s
Explanation:
Given that

So distance = 386242560 m
Velocity of light

We know that
Distance = velocity x time
Now by putting then values

t=1.28 s
So the total time = 2 x 1.28
total time= 2.56 s
Regardless of the time of year, the northern and southern hemispheres always experience opposite seasons. This is because during summer or winter, one part of the planet is more directly exposed to the rays of the Sun than the other, and this exposure alternates as the Earth revolves in its orbit.
Given that the design is not shown, for traditional nuclear reactors with control rods, the best way to meet an increased demand for energy would be to raise the control rods so that less neutrons are absorbed.
So, the most reasonable answer to the question is B.
