Step 1: Analyze the resistance of a copper wire (Question 36). The resistance R of a wire is given by the formula R = (L)/(A), where is the resistivity of the material, L is the length of the wire, and A is the cross-sectional area. For a wire with radius r, the cross-sectional area is A = r^2. Statement 1: It is proportional to the radius of the wire. Substituting A = r^2 into the resistance formula, we get R = (L)/( r^2). This shows that R is proportional to $
