A conducting rod is pulled horizontally with constant force F=3.90N along a set of rails separated by d=0.340m. A uniform magnetic field B=0.800T is directed into the page. There is no friction between the rod and the rails, and the rod moves with constant velocitv v=5.70m/s. Using Faraday's Law, calculate the induced emf around the loop in the figure that is caused by the changing flux. Assign clockwise to be the positive direction for emf. Tries 0/15 The emf around the loop causes a current to flow. How large is that current? (Aqain, use a bositive value for clockwise direction.) Tries 0/15 From your previous results, what must be the electrical resistance of the loop? (The resistance of the rails is negligible compared to the resistance of the rod, so the resistance of the loop is constant.) Tries 0/15 The rate at which the external force does mechanical work must be equal to the rate at which energy is dissipated in the circuit. What is that rate of enerav dissination (power dissipated)? Tries 0/15
