A conductor and a switch
This seems like a question from an electrical course, and is probably best answered by your course materials. It's your test question, not ours, and there won't always be someone to ask the answer of. Earn your diploma.
Magnetism is a force not a substance. As such it can not be applied to paper.
they coat the sheet of paper in a positive charge so that the paper has no static build up
It is called Cuticle and composed of cutin, a wax like material which is chemically a hydroxy fatty acid
The enamel on your teeth is the hardest substance your body produces or is made of.
No, polythene is a plastic and that cannot conduct electricity.
In low voltage wires, the insulation factor of the coating determines the wire's voltage rating. A wire coating of cross linked poly vinyl is used as an insulation. High voltage transmission wires uses no coating on the wire
A coat hanger is a horrible conductor of electric current. Doubt if it would work. Also most distributor wires are hot. Since coat hangers aren't coated it could easily ground out.
a coat is an insulator because it keeps heat in
A jacket can be used as an example of a conductor.
it's an insulator. conductors are things like metals or salts.
yes, it's a metal right? most metals conduct heat very well...

the protein coat.
Because the fire is making the coat hanger hot because the fire is hot The metal coat hanger is a good conductor of heat.

enrobed? to coat or fully cover an item with a dissimilar substance
