Quizplus · Accepted Answer

The quantization of energy becomes important when the level spacing is comparable or larger than the total energy of the system. In the case of a normal mass on a spring, the level spacing is very small compared to the total energy, making quantization unimportant. Planck's constant being larger and Heisenberg's Uncertainty Principle are not relevant to the importance of energy quantization in this case, and choice D is incorrect as quantization applies to all systems, not just atoms.
