A steel wire of length 1.6 m and diameter 0.80 mm is joined to an aluminum wire of identical dimensions to make a composite wire of length 3.2 m. Find the resulting change in length of this composite wire if an object with a mass of 5.00 kg is hung vertically from one of its ends. (Neglect any effect the masses of two wires have on the changes in their lengths.) mm

4.A coaxial cable has an inner core of copper wire with a 3 mm diameter with a current density of 1.768E4 A/m2. The image shows a cross-sectional area of the wire. The current in the core is flowing out of the page. The core is surrounded by a thin sheath of insulating material, 1mm thick. Surrounding this is a thin cylindrical shell of copper wire 1mm thick, that carries the returning current back into the page. The copper shell is...
