Asquare, single-turn coil 0.132 m on a side is placed with its plane perpendicular to a constant magnetic field. an emf of 27.1 mv is induced in the winding while the area of the coil decreases at a rate of 0.0785 m2 /s. what is the magnitude of the magnetic field? answer in units of t.

Calculate the first and second velocities of the car with four washers attached to the pulley, using the formulas v1 = 0.25 m / t1 , and v2 = 0.25 m / (t2 – t1) where t1 and t2 are the average times the car took to reach the 0.25 and the 0.50 meter marks. record these velocities, to two decimal places, in table e.
