PLEASE SHOW WORK FOR ALL STEPS FOR LIFESAVER RATING. THANK YOU

The lightbulb in the circuit shown in the figure(Figure 1) has a resistance of 14 ohm and consumes 5.8W of power, the rod is 1.24m long and moves to the left with a constant speed of 2.9m/s . The strength of the magnetic field is 2.5T. Find the current that flows in the circuit. Express your answer using two significant figures. What speed must the rod have if the current in the circuit is to be 1.2A Express your answer using two significant figures.

Explanation / Answer

V=14*1.2/(1.24*2.5)=5.419354 m/s
