No two electrons in an atom or molecule may have the same four electronic quantum numbers, according to the Pauli Exclusion Principle. Only two electrons can fit into an orbital at a time, hence they must have opposing spins.

<h3>What is Pauli's exclusion principle ?</h3>

According to Pauli's Exclusion Principle, no two electrons in the same atom can have values for all four of their quantum numbers that are exactly the same. In other words, two electrons in the same orbital must have opposing spins and no more than two electrons can occupy the same orbital.

The reason it is known as the exclusion principle is because it states that all other electrons in an atom are excluded if one electron in the atom has the same specific values for all four quantum numbers.

Some iron has a coefficient of linear expansion of 12 x 10-6 / o K . A 100 mm length of iron piping is heated through 20 K. The

VLD [36.1K]

Given that the linear expansion of the pipe is 12×10¯⁶ K¯¹, the pipe extends by 0.024 mm

<h3>Data obtained from the question </h3>

Original length (L₁) = 100 mm
Change in temperature (ΔT) = 20 K
Coefficient of expansion (α) = 12×10¯⁶ K¯¹
Change in length (ΔL) =?

<h3>How to determine the new diameter </h3>

α = ΔL / L₁ΔT

12×10¯⁶ = ΔL / (100 × 20)

12×10¯⁶ = ΔL / 2000

Cross multiply

ΔL = 12×10¯⁶ × 2000

ΔL = 0.024 mm

La tierra aplica una fuerza de atracción de 1000 N sobre un satélite de comunicaciones. La masa del satélite es más de un millón

vaieri [72.5K]

Answer:

La magnitud de la fuerza aplicada por el satélite sobre la Tierra es de 1000 N

Explanation:

De acuerdo con la tercera ley del movimiento de Newton, tenemos que para cada acción (fuerza), aplicada en el universo, existe una fuerza de reacción igual y opuesta

Por lo que un objeto A ejerce una cantidad de fuerza sobre otro objeto B, entonces la fuerza ejercida por el objeto B sobre A es igual en magnitud y opuesta en dirección a la fuerza que proviene del objeto A

Por lo tanto, dado que la Tierra ejerce una fuerza de 1000 N sobre el satélite, entonces la magnitud de la fuerza que el satélite también ejerce sobre la Tierra = 1000 N

A proton moves through a region of space where there is a magnetic field B⃗ =(0.64i+0.40j)T and an electric field E⃗ =(3.3i−4.5j

fenix001 [56]

Answer:

$F = (8.35 \times 10^{-16})\hat i - (12.12 \times 10^{-16})\hat j +(1.35 \times 10^{-16})\hat k$

Explanation:

When a charge is moving in constant magnetic field and electric field both then the net force on moving charge is vector sum of force due to magnetic field and electric field both

so first the force on the moving charge due to electric field is given by

$\vec F_e = q\vec E$
