allerySteel needs 2000 N for a stretch that copper manages with 1100 N. So steel is:
AMuch lighter
BMore elastic
CLess elastic
DMuch softer
Answer & Solution
Correct answer: B. More elastic
1. More force for the same strain means a larger modulus.
2. In physics a larger modulus means more elastic.
3. So steel is more elastic than copper.
