Acircular loop of radius 11.7 cm is placed in a uniform magnetic field. (a) if the field is directed perpendicular to the plane of the loop and the magnetic flux through the loop is 8.60 10-3 t · m2, what is the strength of the magnetic field?

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.
