Answer:
Explanation:
Potential energy builds as the coaster is going up the loop-the-loop and converts to kinetic energy on the way down and out of the loop-the-loop. The potential energy of the coaster is at its lowest and the kinetic energy is at its highest as the coaster moves in the lowest point of the loop-the- loop.
Answer: the neon gas will possess a greater kinetic energy
Explanation:
The neon gas is smaller in mass than the krypton gas. At the came temperature and pressure, the has with a lesser mass will have greater kinetic energy and move faster than the gas with a greater mass. This follows from Graham's law of diffusion in gasses.
