Two resistors of 5.0 and 9.0  are connected in parallel. A 4.0- resistor is then connected in series with the parallel combination. A 6.0-V battery is then connected to the series-parallel combination.
 
  (a) What is the current through the 4.0- resistor?
  (b) What is the current through the 5.0- resistor?
  (c) What is the current through the 9.0- resistor?

Question 2

A camper is about to drink his morning coffee. He pours 400 grams of coffee, initially at 75.0C into a 250-g aluminum cup, initially at 16.0C.
