ות 24). If you were to treat a maglev train (1 = 120 m, m= 75,000 kg)) as a long wire and wanted to levitate it with magnetic force, how strong would the magnetic field have to be to support the weight of the train? Assume the current running through the train is 500 A. 25). You have two polarizers that are tilted 45° w.ct each other. The initial intensity of light is 1050 W/m². What is / after light passes through the two polarizers? If you now put a third polarizer that is tilted at 23°w.rt the first polarizer, what is the final value of l?
