How Do You Calculate Young's Modulus from Wire Stretching Data?

[cstout]

Homework Statement

A wire of length 4.97 m with a cross-sectional area of 0.104 cm2 stretches by 6.52 mm when a load of 0.92 kN is hung from it. What is the Young's modulus for this wire? Answer in Pa

Homework Equations

F/A = Y(Change in L / L)

where F is the magnitude of force
A = .104cm^2
Y= Young's modulus
Change in L = 6.52mm
L = 4.97 m

The Attempt at a Solution

I tried Y = (9025.2 N)(4.97 m) / (.00652 m)(.00104 m^2) but that is wrong

Check your decimal points. F = 920N and A = .0000104m^2
