For Questions 1, 2, 3, and 4. A rear-window de-icer in a car consists of 13 resistive wires connected in parallel to a 12-volt battery. The de-icer has to be able to melt 2.1 x 10-2 kg of ice at 0°C to liquid water at 0°C in 5 minutes. Each wire is 1.3m long. Question 1 How much energy in Joules does each wire have to put out? Question 2 How much power in Watts does each wire have to emit? Question 3 What does the resistance in ohms of each wire have to be? Question 4 What is the resistance/meter of the resistive wire?

A rear window defroster in a certain car is made of 10 identical resistive strips, each of 8.00-12 resistance, connected as shown on the figure and powered by a 12.0-V car battery. It is installed on a 120cm x 60cm window, that is covered by a 0.500-mm thick layer of ice. How long would it take to have all the ice melted using the heat supplied by the defroster? Assume no heat is lost to the surroundings, and the ice/window...
