Opposite sides of the universe have the same temperature, yet according to the standard big bang theory these points are too far apart for light to have traveled from one side to the other in the age of the universe; i. e., they cannot have exchanged heat to even out their temperature. why, then, do they have the same temperature?

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?
