A hanging wire made of an alloy of iron with diameter 0.09 cm is initially 2.2 m long. When a 66 kg mass is hung from it, the wire stretches an amount 1.12 cm. A mole of iron has a mass of 56 g, and its density is 7.87 g/cm³. Based on these experimental measurements, what is Young's modulus for this alloy of iron?
