2. An aluminum (p=2.7x10-2m) wire has a cross-sectional area of 5.1x107 m?. A. If the wire is cylindrical, what is the radius of the wire? B. What is the resistance of 8.3 m of the wire? C. If another aluminum wire has twice the cross-sectional area but the same length, is its resistance larger than, smaller than, or the same as the first wire? Explain. D. What is the resistance for 8.3 m of the wire if the cross-sectional area is 2.7x107 m??
