Answer 1

Answer:

All up time is up never sup

Answer 2

Answer:

The value of gyromagnetic ratio g is equal to 2.0023 for (A) free electrons​.

Explanation:

• In physics, the gyromagnetic ratio refers to the ratio of the magnetic momentum (magnetic dipole moment) in a spinning charged particle to its angular momentum.

• The gyromagnetic ratio (also called g- factor) denoted by "γ" is different for each nucleus of different atoms.

• A Soviet physicist Zavoiski in the year 1945, discovered the phenomenon of electron spin resonance which is used in ESR spectroscopy.

• For a free electron, the value of g is 2.0023. In many free radicals, the value of an odd electron is close to a free electron value.

• This splitting of spin is expressed by gβH.

where g is the g factor

β is the value of the Bohr magneton,

H  is the magnetic field intensity.

• The value of the g-factor is equal to $2.0023$ in the case of "spin only" (since the unpaired electrons possess less contribution towards the magnetic moment.)

Hence Option (A) free electrons​ is correct.
