B. The Particles Have Less Kinetic Energy than those of..
The energy changes involved when a positive charge moves because of a nearby, negatively charged object because that is actually similar to when an object falls in a gravitational field, the potential energy of the object will turn in to a kinetic energy. thank you for this question.
Iron, cobalt, and nickel are elements with a magnetic field.
So,
Solids - definite shape, definite volume Liquids - no definite shape, definite volume
