Two metal rods, one copper, the other lead, are connected inparallel with a temperature of 21 °c at one end and 110°c at the other end. both rods are 0.613 m in length, and the lead rod is 2.61 cm in diameter. if the combined rate of heat flowthrough the two rods is 32.5 j/s, what isthe diameter of the copper rod?

A5 nc point charge is at the origin and a second 3 nc point charge is on the x-axis at x = 0.8 m. find the magnitude and direction of the electric field on the x-axs at x = 0.2 m. you may express the direction by letting positive field mean the positive x direction
