Read the following passage and answer the questions
Aunt Jackie's Ring.
For Mary's birthday, her aunt gave her a ring that was more than 100 years old. "Take good care of it," her aunt warned. She did just that until are day Mary looked down at her hand and noticed the ring was gone.
Aunt Jackie is going to be or disappointed in me, thought Mary. Then Mary remembered she put the ring in her pocket when she washed her hands at the sink. Thank goodness! Mary said to herself. After that, she never took off Aunt Jackie's ring again.

A piece of copper wire has twice the radius of a piece of steel wire. Young’s modulus for steel is twice that of the copper. One end of the copper wire is joined to one end of the steel wire so that both can be subjected to the same longitudinal force. By what fraction of its length will the steel have stretched when the length of the copper has increased by 1%?
