Question 176964: the resistance of copper wire varies directly with its length. a copper wire 275 feet long has a resistance of 950 ohms. what is the resistance of 1575 feet of copper wire Answer by Earlsdon(6294) (Show Source):
You can put this solution on YOUR website! You can start by writing the equation of variation in which R = resistance in ohms and L = wire length in feet, and k = the constant of variation: Solve for k. Substitute the given R = 950 ohms and L = 275 feet and solve for k. Simplify. , so... Substitute L = 1575 feet and solve for R. ohms.
