NAME PHYS-1200 PHYSICS II QUIZ 2 MARCH 30, 2005 SOLUTIONS PART A. 1. B 7. B 2. B 8. E 3. B or D 4. E 5. D 6. D PART B . 1. TO THE BOTTOM OF THE PAGE From Lenz’s law, the direction of the induced electric field will oppose the change that caused it. Therefore it must point clockwise around the magnetic field area. 2. a) TO THE TOP OF THE PAGE The current is going around the circuit in a clockwise direction, so it goes toward the top of the page on the left side of the circuit. The displacement current is in the same direction as the conventional current. b) VOLTAGE AT A = VOLTAGE AT B When the current is a maximum, the capacitor is uncharged, and dt di = 0. Therefore there is no voltage difference between A and B . 3. The speeds of the source and detector that are used in the Doppler equation are measured relative to the air . When a wind blows, it is the same as if both the source and detector are moving through the air at the same speed, and their effects cancel. a)
