A 1.00m long wire with a diameter of 0.02 m stretches by 0.03m when a 20,000-N force is applied to one end as the other is held fixed. Consider an identical wire, except that it has a length of 2.00m. If a 20,000-N force is applied to it, how much will this new wire stretch?

It won't be change. The "new" wire stretches 0.03m again. Length, diameter and the others are not important for our calculation. As indicated in Hooke's Law$$F = -kx$$ Everything about stretch length depends on force and wire constant. So that, if we use the same wire and same force, we get same stretch.
