Particles in the plasma move randomly, but particles in a solid vibrate in one place.

coil wire, increase current, put iron inside the coil

the chart show the masses and velocities of two colliding objects that stick together after a collision.

according to the law of conservation of momentum, the momentum of the object after the collision is  

answer

1,500
