Answerswhich of the following best explains what happens when the kinetic energy of particles in a gas state decreases? (2 points) they vibrate so quickly that the particles ionize and become plasma. they vibrate so slowly that the particles are no longer held together, resulting in a plasma. they move fast enough to overcome the forces of attraction holding them together and become a liquid. they move more slowly, causing the forces of attraction holding them together to increase, resulting in a liquid.

Astone is thrown with a speed v0 and returns to earth, as the drawing shows. ignore friction and air resistance, and consider the initial and final locations of the stone. which one of the following correctly describes the change δpe in the gravitational potential energy and the change δke in the kinetic energy of the stone as it moves from its initial to its final location? options a.δpe = 0 j and δke = 0 j b.δpe is positive and δke is negative c.δpe = 0 j and δke is positive d.δpe is negative and δke is positive e.δpe = 0 j and δke is negative

Complete these sentences. if a roller coaster train has a potential energy of 1,500 j and a kinetic energy of 500 j as it starts to travel downhill, its total energy isj. once the roller coaster train gets closer to the bottom of the hill, its kinetic energy increases to 1,100 j, and its potential energy decreases to j. when the train reaches the bottom of the track and is traveling along the ground, its kinetic energy isj.
