A 0.75 kg ball moving at 3.9 m/s to the right collides head-on with an identical ball moving at 3.9 m/s to the lift in a perfectly inelastic collision. Find the common velocity of the balls and the decrease in kinetic energy during the collision.

adding a(n) to an electric circuit would increase the magnetic field around a wire;

b. solenoid

a solenoid is a type of electromagnet whose purpose is to generate a controlled magnetic field.

if the purpose of the solenoid is instead to impede changes in the electric current, a solenoid can be more specifically classified as an inductor rather than an electromagnet.

i just did an experiment like this in my science class. also the answer is yes, it will get separated because they are two opposites meaning if they are opposite they can not attract.

hope this .!
