Yes, resistance in a conductor causes energy losses due to heat. Metals such as Gold and Platinum have very low resistance but they are very expensive so Copper and Aluminium are used instead which are much more affordable but have higher resistance.
If you are referring to a radioactive material, that will depend on the material. Different things have very different half-lives.
Thermal conductivity is an intensive property. It is inherent in the material but not dependent on the amount of material. This should not be confused with the rate of heat conduction which can depend on the dimensions of a material. There is one case where the thermal conductivity might depend on the dimension of the material - when the conductivity is not uniform with direction, i.e. where conductivity laterally is different from conductivity longitudinally. When the orientation of the material changes the conductivity, the dimensions can have an effect on the apparent bulk thermal conductivity.
Resistance R =p(L /A)i,e Resistance(R) of a conductor will be directly proportional to its length(L) ==> if the length of the conductor increases its resistance also will increase.i,e Resistance(R) of a conductor is inversely proportional to its cross section area(A) ==> if the Area of the conductor increases its resistance also will decrease.

No, the amount of barf is contingent upon how much material is in the stomach.
Sweetness does not depend on the amount of material. It is an intensive property.
Resistance of a material is depend on the force required to withdraw electrons from the atoms of that material.
what type of material the pipe is made out of.
Yes. Radiation is emanated from radioactive material, so the amount of radiation that someone "gives off" is a function of how much radioactive material they have inside them.
It is true.

Intensive because it doesn't depend on the amount of material.
