A 10.0 m2 area wall is constructed of three layers. The first layer is 2.00 cm thick and has a thermal conductivity 0.500 W/mK.
 
  The second layer is 15.0 cm thick and has a thermal conductivity 0.100 W/mK. The third layer is 3.00 cm thick and has a conductivity 1.00 W/mK. How much heat flows through this wall per hour if one side of the wall is at 20.0C and the other side is at 0.00C?
  A)
 
  3.22  105 J
 
  B)
 
  1.73  105 J
 
  C)
 
  4.59  105 J
 
  D)
 
  1.14  105 J
 
  E)
 
  2.68  105 J

Answer to Question 1

C

Answer to Question 2

When two or more waves pass through the same region of space at the same time, it is found that for many waves the actual displacement is the vector (or algebraic) sum of the separate displacements.
