made from pure metals . . . no;
they've been made from all kinds of weird compounds and alloys.
conduct electricity with zero resistance . . . yes;
that's why they're called "superconductors".
produce a strong magnetic field . . . possible, but not because it's a superconductor;
just like any other conductor, the magnetic field depends on the current that's flowing in the conductor.
no loss of energy in the transfer of electricity . . .
there's no loss of energy in the current flowing in the superconductor;
but if you tried to transfer the current out of the superconductor into
something else, then there would be some loss.
20/45=0.4*100= 44.4 so the answer is..................................................
Answer: 44.4%
Answer:
2,800 n
Explanation:
hope this helps, have a nice day/night! :D
In the circuit outside of the battery the electrons have to expend all of their energy on the internal resistance of the battery which causes heating
