The rear window of a car consists of thirteen thin wires (resistivity = 88.0 * 10^-8 ohms) embedded in the glass. The wires are connected in paraellel to the 12.0 Vbattery, and each has a length of 1.30m. The defogger can melt 2.10*10^-2kg of ice at 0 degrees celcius into water at 0 degrees celcius in two minutes. Assume that all the power delivered to the wires is used immediately to melt the ice. Find the cross-sectional area of each wire.
