If the length of substance has been doubled, there will be no effect on resistivity.

Reason

Because resistivity doesn't depend on length. It depends on temperature and nature of material.

However, resistance of substance would be doubled.

Answer 2

Answer: it will increase four time its initial value.....

I hope it be...

Hope it helps u
