An electric circuit has a battery with an EMF of 1.50 V. Its positive terminal is connected to its negative terminal by a copper wire in a circular loop having a radius of 0.500 m. Solve for the drift velocity in the wire if there is one free electron per copper atom. Detailed assumptions: - The size of the cell is negligible compared to the length of the circuit. - Copper resistivity: ρ = 1.80x10-8 Ω-m - Copper density: D = 8.96x103 kg-m-3 - Copper relative atomic mass: ma = 63.5 g/mol Express your answer in mm/s.
