It's because of the position of tectonic plates.
Potential energy due to gravity
The resistance is 4 times the resistance of the first wire. the formula is R = p*l/A with p being resistivity, l length and A area. So if you double length and half area, which botv result in more resistance, you get p*2/0.5 or 4 (p can be abandoned because it is the same. We take standard length and area as 1)
Answer:
I may be wrong
Explanation:
it it won't collapse because it is like a log logs don't sink when they are in water
