The mass of the resistor is 57. how much does the, Ask an Expert

Academics

A 21-cm-long, zero-resistance wire is pulled outward, on zero-resistance rails, at a steady speed of 1.0 in a 0.10 magnetic field (See the figure). On the opposite side, a 1.0 carbon resistor completes the circuit by connecting the two rails. The mass of the resistor is 57 . How much does the temperature of the carbon increase if the wire is pulled for 10 ? The specific heat of carbon is 710.
