Which observation is explained by the Pauli exclusion principle? A. Each atom can be described by a set of allowed energy levels

B. Light can be emitted when an excited electron returns to ground state

C. An electron experiences slight shifts in energy levels in a magnetic field

D. All of the electrons in the ground state of a complete atom cannot be in the lowest energy states

Imagine an isolated positive point charge q (many times larger than the charge on a single proton). there is a charged particle a (whose charge is much smaller than charge q) at a distance from the point charge q. on which of the following quantities does the magnitude of the electric field created by charge q at particle a's position depend? check all that apply.the type of the charge on the charged particle athe relative orientation between q and a (while the distance between q and a is fixed)the specific location of the charged particle a (while the distance between q and a is fixed)the amount of the charge on the point charge qthe specific location of the point charge q (while the distance between q and a is fixed)the distance between the point charge q and the charged particle athe amount of the charge on the charged particle a
