What is neutral buoyancy
What do you mean by the term neutral buoyancy? Briefly illustrate it.
Expert
Buoyancy is the total upward force experienced by the object submersed in the fluid. Pascal's principle states that fluid pressure on an object rises with depth, thus there is a greater pressure on the bottom of object than the top, resultant in a total upward force. Whenever an object's buoyancy is bigger than its weight, then the object will float.
Briefly define or explain the cause of Brownian motion?
Mach's principle (E. Mach; c. 1870): The inertia of any specific particle or particles of matter is attributable to the interaction among that piece of matter and the rest of the world. Therefore, a body in isolation would contain no inertia.
Briefly state the atomic model which the Erwin Schrodinger creates?
Standard quantum limit: It is the limit obligatory on standard techniques of measurement by the uncertainty principle in quantum mechanics.
Bragg's law - Whenever a beam of x-rays strikes a crystal surface in which the layers of ions or atoms are often separated, the maximum intensity of the reflected ray takes place when the complement of the angle of incidence, theta (θ), the wave

Young's experiment: double-slit experiment (T. Young; 1801): A well-known experiment that exhibits the wave nature of light (and certainly of other particles). The light is passed from a small source into an opaque screen with the two thin slits. The
Reflection law: For a wave-front intersecting a reflecting surface, the angle of incidence is equivalent to the angle of reflection, in the similar plane stated by the ray of incidence and the normal.
