An incandescent lamp is operated at 120 V, and the current is 0.5 A. So, the resistance of the lamp is:

Determine in symbols an expression for the magnetic force exerted on the falling bar (and determine the direction of that force). Remember that an electric current passes through it, and the bar is falling in the magnetic field.
