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.

Two 1.20-m nonconducting wires meet at a right angle. one segment carries + 2.50 µc of charge distributed uniformly along its length, and the other carries - 2.50 µc distributed uniformly along it, as shown in fig. 21.50. ( a. find the magnitude and direction of the electric field these wires produce at point p, which is 60.0 cm from each wire. ( b. if an electron is released at p, what are the magnitude and direction of the net force that these wires exert on it?
