A 120-V rms voltage at 1.00 kHz is applied to a resistor and an inductor in series. If the impedance of this circuit is 110 , what is the maximum value of the current?
 
  A) 1.54 A B) 1.04 A C) 1.84 A D) 1.09 A

Question 2

An aluminum rod is 10.0 cm long and a steel rod is 80.0 cm long when both rods are at a temperature of 15C. Both rods have the same diameter.
 
  The rods are now joined end-to-end to form a rod 90.0 cm long. If the temperature is now raised from 15C to 90C, what is the increase in the length of the joined rod? The coefficient of linear expansion of aluminum is 2.4  10-5 K-1 and that of steel is 1.2  10-5 K-1.
  A) 0.90 mm
  B) 0.81 mm
  C) 0.72 mm
  D) 0.63 mm
  E) 0.99 mm

There can actually be a 25-hour time difference between certain locations in the world. The International Date Line passes between the islands of Samoa and American Samoa. It is not a straight line, but "zig-zags" around various island chains. Therefore, Samoa and nearby islands have one date, while American Samoa and nearby islands are one day behind. Daylight saving time is used in some islands, but not in others—further shifting the hours out of sync with natural time.
