Answer:
magnetic separation is the process of separating components of mixtures by using magnets to attract magnetic objects. the process that is used for magnetic separation detaches non-magnetic material with the ones that <em>are </em>magnetic.

<span>There are three main types of pulleys: fixed, movable, and compound. A fixed pulley's wheel and axle stay in one place. A good example of a fixed pulley is a flag pole: When you pull down on the rope, the direction of force is redirected by the pulley, and you raise the flag.</span>
Friction has to do with this. If you have a smoother surface than another surface, the smoother surface will contain less friction. Friction is an opposing force against a moving object. If there is less opposing force towards a moving object, there is less friction. If you have a smooth road, cars won't break as fast as they would break on bumpy roads, because bumpy roads have more bumps, creating more friction. I hope that helped. :D
Answer:
Explanation:
Given
Initially A moves towards Y axis with a velocity of 2 m/s and B moves towards X axis with velocity of 3.7 m/s
mass of both the block is same let say m
Conserving momentum in x direction
thus A moves with a velocity of 3.7 m/s towards x axis in order to conserve the momentum in x direction
Thus ball B moves towards Y direction with
And ball A moves towards X direction with
(c)Total momentum
