1 mile long copper wire has a resistance of 10 ohms. What will be its new resistance when it is shortened by cutting it in half?

I'm not sure, but I don't think the resistance would change.

Well, assuming that the ohms per foot on the wire is a constant, if 1 mile is 10 ohms, then a half-mile would be 5 ohms.

Half the length, half the resistance.
