why quantum physics is studied? give me some of topics
Describe why is heavy water employed as a moderator? Illustrate.
What is Archimedes' principle? A body which is submerged in a fluid is buoyed up by a force equivalent in magnitude to the weight of the fluid which is displaced, and directed upward all along a line via the c
Explain what does held the nucleons altogether in a nucleus?
What is main difference between secondary electron image and the back scattered electron image? State briefly.
Magnus effect: The rotating cylinder in a moving fluid drags a few of the fluid about with it, in its direction of rotation. This raises the speed in that area, and therefore the pressure is lower. Therefore, there is a total force on the cylinder in
What do you mean by the term neutral buoyancy? Briefly illustrate it.
Planck equation: The quantum mechanical equation associating to the energy of a photon E to its frequency nu: E = h nu.
Bernoulli's equation - In an ir-rotational fluid, the sum of static pressure, the weight of the fluid per unit mass times the height and half of the density times the velocity squared is steady all through the fluid
