When two magnets are brought together, the opposite poles will attract one another, but the like poles will repel one another. This is similar to electric charges. Like charges repel, and unlike charges attract.

Answer:
They diverge on refraction
Explanation:
When parallel light rays strike a concave lens, they will diverge that is they spread out .
Concave lens is also known as diverging lens, which means that when parallel rays of light strike on it, the lens spreads out the light rays ( that is it diverges the rays of light) that are refracted through it.
At the middle of concave lens is thinner.
When light is passes through the lens they diverge it or spread out.
The concave lens causes light rays to bend away or diverge from its axis since the concave lens is a diverging lens.
The correct answer is: +5
Explanation:
An object is placed at 0; it means:
Initial position of the object = 0.
Now it moves to 3 units to right, so keeping the standard cartesian coordinate system in mind (in right right x-axis is positive and left x-axis is right), the new position of the object will be +3.
Object now moves 4 units to the left, it means +3 - 4 = -1; object is at the position -1.
Object then moves 6 units to the right, therefore,
Final position of the object = -1 + 6 = +5.
Displacement = Final position - Initial position
Displacement = +5 - 0 = +5
