10 Points In the diagram, there is a magnetic field in the +x direction with B = 0.20 T.  The loop has an area of 5.0 cm2 and rotates about the line CD as an axis.  Point A rotates toward positive x values from the position shown.  If line AE rotates through 50° from its indicated position in a time of 0.20 s. What is the change in flux through the coil? What is the average induced emf in it? Does the induced current flow from A to C or C to A in the upper part of the coil?

10 Points A metal rod makes contact with a partial circuit and completes the circuit.  The circuit area is perpendicular to a magnetic field with B = 0.15 T.  If the resistance of the total circuit is 3 Ω, how large a force is needed to move the rod as indicated with a constant speed of 2 m/s?

10 Points The diagram shows a parallel plate capacitor of plate area 10.5 cm2 and plate separate 2d = 7.12 mm.  The left half of the gap is filled with material of dielectric constant K1 = 21.0; the top of the right half is filled with a material of dielectric constant K2 = 42.0; the bottom of the right half is filled with a material of dielectric constant K3 = 58.0.  What is the capacitance?
