Answer;

C. never become laws; based on strong scientific support; may change based on evidence.

Explanation;

-A scientific theory is a generally accepted, thoroughly tested and confirmed explanation for a set of observations or phenomena. Scientific theory is the foundation of scientific knowledge.

-In addition, in many scientific disciplines (less so in biology) there are scientific laws, often expressed in mathematical formulas, which describe how elements of nature will behave under certain specific conditions.

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
