I need helpo with this. I need step by step solutions for this and I cant figure it out.
Wire to be used in buildings and homes in the United States is standardized according to the AWGsystem (American Wire Gauge). Wires are assigned a gauge number according to their diameter.The scale ranges from gauge 0000 to gauge 36 in 39 steps. The equation for the wire gauge interms of the wire diameter in millimeters is as follows.Answer the following questions with your group.(a) What is the equation for the diameter in millimeters in terms of the wire gauge N?(b) You have two wires, one that has five times the diameter of the other. By how much do thewire gauges differ for the two wires? (Give your answer to the nearest integer.)
