The imаge belоw shоws а clоsed loop of height ho = 11 m аnd length L = 5 m, consisting of parallel metal rails connected on the bottom by another metal rail (all of which have negligible resistance), and a crossbar. The mass of the crossbar is 1.2 kg and its resistance is 250 Ω. There is a uniform magnetic field, B0 = 3.0 T pointing into the page. a.) What is the magnetic flux through the closed loop shown above? (1 point) b.) The crossbar begins to fall (from rest) with negligible friction as it maintains contact with the metal rails. Is the direction of current induced in the loop clockwise or counterclockwise? Explain (1 point) c.) Determine the amount of current through the loop as a function of the crossbar's speed, v. (1 point) d.) Write, but do not solve, a differential equation that could be used to describe the crossbar's velocity as a function of time. (2 points) e.) What is the terminal velocity of the crossbar? (1 point) f.) If the crossbar was replaced by one of identical mass but more resistance, how would its terminal velocity compare to the terminal velocity of the original crossbar? Explain. (1 point)
