Relate the changes in molecular motion of particles as they change from solid to liquid to gas. As the phase changes occur, the freedom of motion of the particles

increases.

As the phase changes occur, the freedom of motion of the particles

decreases.

As the phase changes occur, the freedom of motion of the particles

compresses.

As the phase changes occur, the freedom of motion of the particles is

constant.

When a colid cuch as ice begins to melt heat energy is added. What is the function of this added heat

Two thin 80.0- cm rods are oriented at right angles to each other. each rod has one end at the origin of the coordinates, and one of them extends along the x- axis while the other extends along the yaxis. the rod along the x- axis carries a charge of - 15.0 μ c distributed uniformly along its length, and the other rod carries 15.0 μ c uniformly over its length. find the magnitude and direction of the net electrical force that these two rods exert on an electron located at the point (40.0 cm, 40.0 cm).
