A conducting rod of length 40.0 cm is free to slide on two parallel conducting bars. A resistor R=5.00 N is connected to the end of the bar. The conducting bar and the rod have negligible resistance. A constant magnetic field B=2.50 T is directed perpendicularly into the page. An external agent pulls the rod to the left with a constant speed of v=10.0 m/s. What is the power dissipated in the resistor? Give your answer in W.
