When current is flowing through the conductor that is placed in a magnetic field there is a force acting on the conductor. This force is called the Lorentz force, and in fact, whenever you have a charge moving in the magnetic field there is a force acting on it that is perpendicular to its motion. Lorentz force is very interesting as it does not change the speed of the charge only its direction.
In a conductor, there is a constant motion of electrons and if you put them in the magnetic field you get the force.
Electromotor always has a static part, which is just a permanent magnet, and it has the conductor. I attached a sketch of a very simple electromotor.
If you trace the current along the conductor you will notice that for some part it is moving away from you and for some part, it is moving towards you. Because of this the forces on opposite sides of the conductor act in the opposite directions and create the torque that makes the conductor rotating.
The basic statement could be something like this:
When there is a current flowing through the conductor it acts as a magnet. If you put that conductor in the permanent magnetic field there will be a force that acts on it. If you carefully arrange the shape of the conductor you can achieve continual motion.
Status refers to a person's prestige, social honor, or reputation in society. Weber stated that political strength become now not rooted entirely in capital fees, but additionally in a single's individual popularity. Poets or saints, for example, can own a massive impact on society, often with little monetary worth.
The German sociologist Max Weber formulated a three-component theory of stratification that defines a status group (additionally status class and status estate) as a group of humans within a society who can be differentiated by means of non-financial characteristics along with honor, prestige, ethnicity, race, and religion.
Social stratification entails society as a system of hierarchical categories. Max Weber defined stratification because the division of a society into distinct communities, that have varying assignments of “status honor” or status.

Answer:
Ratio D/h of minimum viewing distance to screen height is 16.28
Explanation:
Given the data in the question;
Rayleigh criterion sin = 1.22 λ/D
D is diameter (5.12 mm) = 5.12 × 10⁻³
λ is wavelength ( 537 nm) = 537 × 10⁻⁹ m
so we substitute
sin = 1.22 × 537 × 10⁻⁹ / 5.12 × 10⁻³
sin = 655.14 × 10⁻⁹ / 5.12 × 10⁻³
sin = 0.000127957
= sin⁻¹ ( 0.000127957 )
= 0.007331°
now, tan = y/D
y = h/480
so
tan = h/480 / D
h/D = 480 × tan
D/h = 1 / ( 480 × tan )
we substitute in value of
D/h = 1 / ( 480 × tan( 0.007331° ) )
D/h = 1 / ( 480 × 0.00012795 )
D/h = 1 / 0.061416
D/h = 16.28
Therefore, Ratio D/h of minimum viewing distance to screen height is 16.28
