Each one is a living organism.
The answer would be c as the cart is not in motion therefor ruling out kinetic and it is completely at rest making all of it energy potential
I would pick the first option in the third option
I would be difficult to remove an electron from a Noble or Inert Gas (also known as the group 8 or 0 elements). This is because they all have filled outermost shells and as such the outermost shell would be held tightly to the nucleus and as such make it difficult to remove. Examples Helium, Neon, Argon, Xenon, Krypton and Radon
It depends on the concentration of ions which are responsible for the electrical conductivity in aqueous solutions.
