Two parallel plates that are initially uncharged are separated by 1.7 mm, have only air between them, and each have surface areas of 16 cm2.
 
  How much charge must be transferred from one plate to the other if 1.9 J of energy are to be stored in the plates? (0 = 8.85  10-12 C2/N  m2)
  A) 5.6 C
  B) 4.0 C
  C) 8.0 C
  D) 0.60 mC

Question 2

The thermal conductivity of aluminum is twice that of brass. Two rods (one aluminum and the other brass) of the same length and cross-sectional area are joined together end to end.
 
  The free end of the brass rod is maintained at 0C and the free end of the aluminum rod is maintained at 200C. If no heat escapes from the sides of the rods, what is the temperature at the place where the two rods are joined together?
  A) 76C
  B) 133C
  C) 148C
  D) 155C
