Question 3 options: when heat gets transferred through objects that are touching when the measurement of heat in the atmosphere goes down when heat gets transferred through electromagnetic waves that move through space when heat gets transferred through a liquid or a gas

What happens to light waves from a star as the star moves away from earth?

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). (e
