Answer: The correct answer is A.
Explanation:
In magnets, there are two poles: South and north poles. Like poles repel each other. Unlike poles attract each other.
When two magnets of the opposite poles are brought together then the poles are attract each other.
When two magnets of the same poles are brought together then the poles are repel each other.
Therefore, the correct answer is A.

The speed of the space craft relative to the earth is given as: 0.024c. This is solved using the the equation for time dilation.
<h3>
What is time dilation?</h3>
Time dilation is the "slowing down" of a clock as determined by an observer in relative motion with regard to that clock under the theory of special relativity.
The formula is given as :
Δt = [Δr]/ √ 1 - (v²/c²)
Thus,
v = c√1 - (Δr/Δt)²
= c √(1 - (3600/3601)²
v = 0.024c
