Step 1: Recall the formula for resistance. The resistance R of a wire is given by the formula: R = ( L)/(A) where is the resistivity, L is the length, and A is the cross-sectional area. Step 2: Substitute the given values into the formula. Given: L = 1.0 m A = 2.9 × 10^-8 m^2 = 4.9 × 10^-7 m R = (4.9 × 10^-7 m)(1.0 m)2.9 × 10^-8 m^2 Step 3: Calculate the initial resistance. R = 4.9 × 10^-72.9 × 10^-8 R = 16.89655... Rounding to three significant figures: R = 16.9 The initial resistance of the wire is 16.9 . Send me the next one 📸
