A steel wire of length 1.7 m anddiameter 1.10 mm is joined to analuminum wire of identical dimensions to make a composite wire oflength 3.4 m. Find the resulting change in length of this composite wire if an object with a mass of5.00 kg is hung vertically from one of its ends. (Neglect anyeffect the masses of two wires have on the changes in theirlengths.)
