What are two key substances that must be present for conduction?

Two key substances needed for conduction are electrons and a conductive material. Electrons serve as the charge carriers that move through the material, while the conductive material provides a pathway for the electrons to flow.


What property determines the choice of material that is used for the inside of an electrical wire and the material that is used for the outside of the wire?

The most important property is the conductivity of the material under consideration. A high conductivity is needed for the inside, and a very low conductivity for the outside. Only after this can we consider other factors, such as cost, strength, toxicity, flammability, flexibility, corrosion resistance and ease of making and shaping.


Is there a material that dynamite or TNT cannot destroy?

Dynamite and TNT destroy things via a shock wave; there is nothing intrinsic about TNT or Dynamite that causes something to be destroyed (i.e. the explosion could just as easily have been produced by any other explosive material).All (solid or semi-solid) materials have a fracturing point, and can thus be "destroyed" by an explosive. The key is how strong the shock wave is when it hits the material, and of course the composition of the material in question.In short, there is no answer to your question, other than, YES, TNT can theoretically defeat any material, given the proper amounts and configuration of TNT, and for certain configurations of the material.
