The temperature coefficient of resistivity for the metal gold is 0.0034 (C°)-1, and for tungsten it is 0.0045 (C°)-1. The resistance of a gold wire increases by 6.5 percent due to an increase in temperature. For the same increase in temperature, what is the percentage increase in the resistance in a tungsten wire?
