What is the energy difference between parallel and antiparallel alignment of the z component of an electron's spin magnetic dipo
Readme [11.4K]

Answer:

\Delta U= 4.8204\times10^{-24} J

Explanation:

The difference between parallel and anti parallel alignment of the z component of an electron's spin magnetic dipole moment  is given by

U_1-U_2= (-\mu Bcos(\theta_2))-(-\mu Bcos(\theta_1))

where  μ= dipole moment B= strength of magnetic field and θ= angle between direction of magnetic field and dipole

here θ_2 and θ_1 are 180 and 0° respectively.

U_1-U_2= (\mu B)-(-\mu B)

U_1-U_2= 2\mu B

here μ is bohr magnetron or  magnetic moment of an electron = 9.27×10^{-24}

put this value we get

U_1-U_2= 2\times 9.27\times10^{-24}(0.26)

\Delta U= 4.8204\times10^{-24} J

Light with a single wavelength falls on two slits separated by 0.510 mm. In the resulting interference pattern on a screen 2.24
scZoUnD [109]

Answer: 655.7 nm

Explanation:

Given

The slits are separated by d=0.510\ mm

Distance between slits and screen is D=2.24\ m

Adjacent bright fringes are \beta =2.88\ mm apart

Also, the distance between bright fringes is given by  

\Rightarrow \beta =\dfrac{\lambda D}{d}\quad [\lambda=\text{Wavelength of light}]\\\\\text{Insert the values}\\\\\Rightarrow 2.88\times 10^{-3}=\dfrac{\lambda \cdot 2.24}{0.510\times 10^{-3}}\\\\\Rightarrow \lambda =\dfrac{2.88\times 10^{-3}\times 0.510\times 10^{-3}}{2.24}\\\\\Rightarrow \lambda =0.6557\times 10^{-6}\ m\\\Rightarrow \lambda =655.7\ nm

  • Uranus is much smaller and less massive than Jupiter.
  • Uranus's appearance is nearly featureless; very bland.
  • Uranus has some large moons and rings.
  • Uranus rotates on its side, giving it extreme seasons. This may have been caused by an impact.

Describe Uranus?

Uranus is described as the seventh planet from the Sun. The name Uranus  is a reference to the Greek god of the sky, Uranus, who, according to Greek mythology, was the great-grandfather of Ares, grandfather of Zeus and father of Cronus.

Some known facts about Uranus includes the following:

  • Uranus is the coldest planet in the Solar System
