Question 11 part 1 of 1 10 points Given: Assume the bar and rails have neg- ligible resistance and friction. In the arrangement shown in the figure, the resistor is 2 2 and a 8 T magnetic field is directed out of the paper. The separation between the rails is 4 m. Neglect the mass of the bar. An applied force moves the bar to the right at a constant speed of 1 m/s. 8 T A O 8 T www 202 m<1 g O 1 m/s At what rate is energy dissipated in he resistor? Answer in units of W.
Question 8 part 1 of 1 10 points The electric field in an electromagnet wave (in vacuum) is described by E = Emax sin(kx-wt), where Emax = 1.5 x 108 m The speed of light is 2.99792 x 108 m/s. Find the amplitude of the corresponding magnetic wave. Answer in units of T. 6.1 N/C and k Question 9 part 1 of 1 10 points A transformer is used to convert 120 V to 4 V in order to power a toy electric train. There are 240 turns in the primary. How many turns should there be in the secondary? Answer in units of turns.
