Metal is a conductor. What this means is that it has a very low resistance to electricity, allowing the electricity to flow through it.
I suggest you learn how electricity works first to understand how electricity can flow through objects.

Electricity can travel throughout freely moving Electrons, like in metal which is in wires under the rubber.
Because electricity will travel through almost everything but wood, rubber, and a few more. Scissors have metal in them, and that is the thing that electricity loves to travel through.
Because electricity can only travel through metal.
If the wrench is made of metal, which almost all are, the answer is yes.
conductors are thing that electricity travels through, metal insulators are things electricity does not travel through, dry wood, paper, plastic.
Yes, electricity can flow through metal.
sound can travel through metal.
Electricity doesn't make metal. Since electricity only travels through it.
Although you cant see them,all over your house there is hundrends of wires passing through walls, and ceilings. The wires have metal in them and electricity passes through the metal and into all sorts of machines that need electricity to power them xx
Yes, sound can travel through metal strings. It can travel through any medium except for vacuum.
Yes it would travel better through metal as the velocity of sound in metal is more than in air.
Depends on the material. The electricity can flow through metal better then it can through wood because wood is a conductor of electricity (example).
