12) Which State of matter has the most particle motion? A)Gas
B)Solid
C)Liquid
D)Crystal

here

Explanation:

A

The three states of matter are solids, liquids, and gases. Particles in solids are densely packed together. The particles in liquids move more quickly, whereas the particles in gases are more evenly distributed. In chemistry, particles can be atoms, ions, or molecules.

question: ray weighs 100 kilograms, his wrestling partner, bobby, weighs 50 kilograms. if ray moves at 4 m s , how fast will bobby have to run at him to apply an equal amount of kinetic energy?

answer: 8 m/s he needs to run twice as fast to keep up so he has some work to do

explanation:   if the mass has units of kilograms and the velocity of meters per second, the kinetic energy has units of kilograms-meters squared per second squared.
