: The coat hanger shown below is made of PVC (polyvinyl chloride). The neck of the hanger is 0.010 m in diameter and is 0.10 m long. If a coat hangs on the hanger, the length of the neck will increase by 1.00 x10 -5 m.

1. What is the mass of the coat?
2. How many such coats must be hung on the hanger to cause the neck to remain stretched after the coats are removed?
