Question 2

An aluminum rod is 10.0 cm long and a steel rod is 80.0 cm long when both rods are at a temperature of 15C. Both rods have the same diameter.
 
  The rods are now joined end-to-end to form a rod 90.0 cm long. If the temperature is now raised from 15C to 90C, what is the increase in the length of the joined rod? The coefficient of linear expansion of aluminum is 2.4  10-5 K-1 and that of steel is 1.2  10-5 K-1.
  A) 0.90 mm
  B) 0.81 mm
  C) 0.72 mm
  D) 0.63 mm
  E) 0.99 mm
