Section 2- Quick Response (50 Points) QR Problem 1 (20 Points) Match the quantities in Column 1 to the appropriate units in Column 2. Write the letter of the appropriate units in the blank to the right of the given quantity. MKS base units are used for all quantities.

Another Dimension Not Listed QR Problem 2 (10 Points) = A primitive DC motor rotor has rotor windings N, 100 turns, a rotor length = 30cm, a radius of r = 10cm. At a particular instant when operating at wm = 3600RPM, we measure a back EMF on the unused stator winding of 227 volts. Estimate the magnetic field produced in the gap by the stator, B, at this instant. HINT: We're in Module 15.
