A certain copper wire that has a cross-sectional area of 11.11 x 10-6 m2 is used to slowly lift and support a 34.6 kg load. If the length of this wire changes by 0.80 mm while the 34.6 kg load is being held in place above the ground, then what was the original length of the wire (in m)? (Note: the value of Young's Modulus for aluminum is 11.0 x 1010 Pa.)
