Three wires meet at a junction. One wire carries a current of 5.2 Amps into the junction, and a second wire carries a current of 3.7 Amps out of the junction. What is the current in the third wire? Give your answer as the number of Amps, and give a positive number if the current in that wire flows out of the junction, or a negative number if the current in that wire flows into the junction.

Suppose a heart defibrillator passes 10.5 Amps of current through a patient's torso for 5.0 x 10-3 seconds in order to restore a regular heartbeat. The voltage across the defibrillator is 9800 volts for the entire time that current is flowing. If 7.25 kg of body tissue is involved, with a specific heat of 3500 J/(kg°C), then what is the resulting temperature increase of the person's torso? (Give your answer as the number of degrees C.)
