Resistivity :

Resistivity is a measure of the resistance to the flow of electrons. 

Conductivity :

Conductivity is just the inverse of resistivity, σ = 1/ρ, where σ is conductivity and ρ is resistivity.

Example:

Think of a pipe and water, the bigger the pipe, the easier water can flow and thus the lower the resistance. 

In general, polar solvents dissolve polar solutes, and nonpolar solvents dissolve nonpolar solutes.
As water molecules are polar, polar molecules dissolves in water.

Any moving object can exhibit kinetic energy, as kinetic energy is also known as Motional energy.

In the given options, only a space station orbiting Earth is in motion and all the other are in rest position.

Hence, option C) a space station orbiting Earth is only exhibiting kinetic energy.

The term 'degrees of newness' is associated with degree of design change. How much the design changes that much newness comes in it.
