A hanging wire made of an alloy of lead with diameter 0.05 cm is initially 2.6 m long. When a 4 kg mass is hung from it, the wire stretches an amount 3.24 cm. A mole of lead has a mass of 207 grams, and its density is 11.4 g/cm3. Based on these experimental measurements, what is Young's modulus for this alloy of lead?
