No two electrons can have the same set of quantum numbers .
<h3>What is Wolfgang Pauli hypothesized an exclusion principle?</h3>
Pauli made a significant advance when he proposed the notion of adding a fourth quantum number to the three that were previously used to represent the quantum state of an electron. Physically speaking, the first three quantum numbers made sense since they had to do with how the electron moved about the nucleus.
The following rule was developed by Austrian physicist Wolfgang Pauli. The quantum numbers of any two electrons cannot be identical.
To put it another way, no two electrons can be in the same state. The Pauli exclusion principle is the name given to this proposition since it forbids electrons from being in the same state.

Answer: Single replacement
Explanation: A P E X
When the angle of the ramp increases, the weight of the box acting perpendicular to the ramp decreases.
<h3>
Normal reaction of the box</h3>
The normal reaction of the box is due to weight of the box acting perpendicular to the ramp.
Fn = Wcosθ
<h3>when the angle of the ramp = 30⁰</h3>
Fn = Wcos(30)
Fn = 0.866W
<h3>when the angle of the ramp = 45⁰</h3>
Fn = W x cos(45)
Fn = 0.7071W
Thus, when the angle of the ramp increases, the weight of the box acting perpendicular to the ramp decreases.

Answer:
θ = 45º
Explanation:
The light that falls on the second polarized is polarized, therefore it is governed by the law of Maluz
I = I₀ cos² θ
in the problem they ask us
I = ½ I₀
let's look for the angles
½ I₀ = I₀ cos² θ
cos θ = √ ½ = 0.707
θ = cos 0.707
θ = 45º
