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.
pls. mark brainliest am. dyning for it
I would say that the answer is C
Answer:
Speed of lighter ball is 4 m/s.
Explanation:
Applying the principle of conservation of linear momentum,
momentum before collision = momentum after collision.
+ 
= 
- 
= 3 kg, = 8 m/s, = 2 kg, = 0 m/s ( since it is at rest), = 2 m/s, = ?
(3 x 8) + (2 x 0) = (8 x 2) - (2 x )
24 + 0 = 16 - 2
2 = 16 - 24
2 = -8
= 
= -4 m/s
This implies that the light ball moves at the speed of 4 m/s in the opposite direction of the heavier ball after collision.
