A hanging iron wire with diameter 0.12 cm is initially 2.85

A hanging iron wire with diameter 0.12 cm is initially 2.85 m long. When a 88 kg mass is hung from it. the wire stretches an amount 1.03 cm. A mole of iron has a mass of 56 grams, and its density is 7.87 g/cme. Find the approximate value of the effective spring stiffness of the interatomic force. Part 1 Your answer is correct. (a) What is the length of an interatomic bond in iron (diameter of one atom)? 2.28c-10 m Attempts: 1 of 5 used Part 2 Your answer is incorrect. (b) Find the approximate value of the effective spring stiffness of one interatomic bond in iron. i N/m
