Question

Hello, I need some help with this problem.

2) A wire made of an unknown alloy hangs from a support in the ceiling. You measure the relaxed length of the wire to be 1.6 m long, and the radius of the wire to be 0.00035 m. When you hang a 5 kg mass from the wire, you measure that it stretches a distance of \(4 \times 10^{-3}\) m. The average bond length between atoms is \(2.3 \times 10^{-10}\) m for this alloy.
