Wolfgang pauli hypothesized an exclusion principle. This principle says two electrons in an atom cannot have the same what?.

PilotLPTM [1.2K]

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.

A large uniform chain is hanging from the ceiling, supporting a block of mass 46 kg. The mass of the chain itself is 19 kg, and

docker41 [41]

Answer:

T = 451.26 N

Explanation:

It is given that,

The mass of block, m = 46 kg

Mass of the chain, m' = 19 kg

Length of the chain, l = 1.9 m

Let T is the the tension in the chain at the point where the chain is supporting the block. It is clearly equal to the product of mass and acceleration.

$T=mg$

$T=46\ kg\times 9.81\ m/s^2$

T = 451.26 N

So, the tension in the chain at the point where the chain is supporting the block is 451.26 N. Hence, this is the required solution.

Metal sphere having an excess of +5 elementary charges has a net electric charge of

Natasha2012 [34]

Answer:

$q=+8.01\cdot 10^{-19}\ coulombs$

Explanation:

<u>Elementary charge</u>

The elementary charge, denoted by the symbol e is the electric charge carried by a proton or, equivalently, the magnitude of a negative electric charge carried by an electron, which has charge −e.

The value of the elementary charge is a fundamental constant in physics:

$\mathbf{e}=1.60217662 \cdot 10^{-19}\ coulombs$

If a metal sphere has an excess of +5 elementary charge, then it has a net charge of:

$q=5*\mathbf{e}=+5*1.60217662 \cdot 10^{-19}\ coulombs$

$\boxed{q=+8.01\cdot 10^{-19}\ coulombs}$
