Question

True or false:
Quantum mechanics is more effective at explaining phenomena that are of "normal" size (larger than a molecule and smaller than a planet), at a "normal" temperature (anywhere close to room temperature), and going a normal speed (from 0 m/s- to anything significantly less than the speed of light).

Answer 1

false,actually we can get any relation through quantum mechanics,but in normal/large particles the obtained value will be comparatively with error,but in case of sub-atomic particle,the answer will come accurately,so it is false.

Answer 2

Thank you!
...How do I give you a medal?

Answer 3

haha,no need.just keep studying.:)
