what is the maximum current imax in a straight superconducting niobium wire of radius 1.5 mm ? keep in mind that the superconductivity of a niobium wire is destroyed if the magnetic field at the surface of the wire reaches or exceeds 0.10 t .

If you touch a hot light bulb and get burned, that is an example of a. radiation b. convection c. conduction

Imagine you had to physically add electrons, one at a time, to a previously neutral conductor. you add one electron very easily, but the second electron requires more work. in your initial post to the discussion, explain why this is. also, what happens to the work needed to add the third, fourth, fifth, and subsequent electrons

Within a pendulum, as potential energy decreases, energy increases. a. heat b. kinetic c. frictional d. gravitational
