An electromagnetic wave has a peak electric field of 3.0 kV/m.
 
  What is the intensity of the wave? (c = 3.0 x 108 m/s, 0 = 4  10-7 T  m/A, 0 = 8.85  10-12 C2/N  m2)
  A) 24 kW/m2
  B) 12 kW/m2
  C) 8.0 kW/m2
  D) 4.0 kW/m2

Question 2

Three resistors having resistances of 4.0 , 6.0 , and 10.0  are connected in parallel. If the combination is connected in series with an ideal 12-V battery and a 2.0- resistor, what is the current through the 10.0- resistor?
 
  A) 0.59 A
  B) 2.7 A
  C) 6.4 A
  D) 11.2 A
  E) 16 A
