The thermal conductivity of aluminum is twice that of brass. Two rods (one aluminum and the other brass) are joined together end to end in excellent thermal contact. The rods are of equal lengths and radii.
 
  The free end of the brass rod is maintained at 0C and the aluminum's free end is heated to 200C. If no heat escapes from the sides of the rods, what is the temperature at the interface between the two metals? A) 76C
  B) 133C
  C) 155C
  D) 148C
  E) 92C

Question 2

A charge of 2.0 C flows onto the plates of a capacitor when it is connected to a 12. V battery. How much work was done in charging this capacitor?
 
  A) 24. J
  B) 12. J
  C) 48. J
  D) 0.14 mJ
  E) 21. J
