Question

Problem 1: You need to prepare a 0.125×10^-3 m diameter tungsten wire with with resistance of 3590. How long must the wire be? The resistivity of tungsten is 5.62×10^-5.

Problem 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 9350 m/s and protons move to the left at 2583 m/s. The particles are evenly spaced with 0.0288 m between electrons and 0.0237 m between protons. Assuming that there are no collisions and that the interactions between the particles are negligiable, what is the magnitude of the average current in this region?
