translucant
Any metal, water, skin and many other substances.
Insulators are materials that resist the flow of electricity. They have high resistivity, preventing the free flow of electrons and reducing the transfer of heat or electricity through them. Common insulating materials include rubber, glass, plastic, and ceramic.
This question is sort of a non-sequitur. I think the answer you want is: a low viscosity fluid.
electricity
Metals conduct electricity as a result of the way they bond to form alloys. Their configuration is like positive ions in an "electron sea", which means that the electricity can travel easily through the electrons.
Cotton wool is not a conductor or an insulator it is a semi conductor. It is sort of in the middle, electrons can travel through cotton wool but not as good as silver, bronze, metal and so on.
Electricity.
No. Material that is directly deposited by glaciers, called till, is completely unsorted. However, some of the processes around glaciers, particularly streams from meltwater, can sort material.
Some sort of seed or something that lets life in its' kind to continue.
There is no "force of electricity". Voltage is sort of like a "force" that makes electricity flow, but it doesn't have the units of force.
coal is used
