A 600-g piece of iron at 100C is dropped into a calorimeter of negligible heat capacity containing 100 g of ice at 0C and 120 g of water, also at 0C.
 
  What is the final temperature of the system? The specific heat of iron is 448 J/kg  K, the latent heat of fusion of water is 33.5  104 J/kg, and the specific heat of water is 4186 J/kg  K.

Question 2

At 1.0 kHz, the phase angle of an RLC series circuit with a capacitive reactance of 40 , a resistance of 100 , and a certain inductor is 40. What is the inductance in this circuit?
 
  A) 12 mH B) 20 mH C) 120 mH D) 62 mH E) 210 mH
