Question

A wire 3. 0 m long has a radius of 0. 35mm. When 7. 0kg loads hung from it, the wire stretches 1. 45mm. What is the Young Modulus for the material of the wire?

Answer 1

3.69×10^11 N/m^2

Step-by-step explanation:

convert the mm to m by multiplying the mm by 10^-3.

remember that young modulus unit is N/m^2 so put the unit in the answer

also note that acceleration due to gravity is acting in the experiment.
