This ain’t the place, bud. If you have a QUESTION, then you can post it here.
Answer:
Explanation:
Given:
- length of a steel-string,
- area of the string,
- Young's modulus of the steel,
- force of tension on the string,
We have the relation for change in length:
To find how far east we drove (This is the displacement), we simple subtract 12 from 40.
An easy way to do this in your head is to round 12 down to 10, subtract 10 from 40, then subtract the remaining 2. This should result in an answer showing that you drove 28 miles east.
I believe it’s A, i could be wrong tho 3
