A 2.0 meter long Aluminum wire (R = 0.44 m,  = 2.82  10-8 -m,  = 4.29  10-3 C-1 ) is connected in series to an 8.0 meter long Tungsten wire (R = 0.20 m,  = 5.6  10-8 -m,  = 4.5  10-3 C-1).
 
  What is the resistance of the combination if the wire is heated to 150.C? Assume the initial temperature for both wires is room temperature (20C). A) 0.78 m
  B) 0.88 m
  C) 0.69 m
