1) Find the drift velocity of conduction electrons in a gold wire of diameter 1.03 mm when a current of 0.221 A flows in it. The density of conduction electrons in gold is 5.90 X 10^28 m-3

____m/s

2) Suppose that a particle accelerator is used to move two beams of particles in opposite directions. In a particular region, electrons move to the right at 7130 m/s and protons move to the left at 1681 m/s. The particles are evenly spaced with 0.0570 m between electrons and 0.0832 m between protons. Assuming that there are no collisions and that the interactions between the particles are negligible, what is the magnitude of the average current in this region?
