If the motor runs for 10 hours, how much will Sw1 heat up (in ° ) if the switch is entirely made of copper. Assume the current in 1 was found to be 600m (which is a reasonable estimate of the result from step 1, but not quite the correct answer) and the mass of the switch is 75. Compare your result to the melting temperature of copper and interpret the results (assume no heat dissipation during the 10 hours).
