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.
Steradian: sr: The supplementary SI unit of solid angle stated as the solid central angle of a sphere which encloses a surface on the sphere equivalent to the square of the sphere's radius.
What is the basic difference among the dynamic strain aging and the strain aging?
Trojan points: L4 and L5 are the two dynamically stable Lagrange points (that is, beneath certain conditions).
Heat pumps move heat from one place to another. They work similar to refrigeration. The movement of heat takes energy, either electrical energy as in the use of vapor compression heat pumps or thermal energy as in the use of absorption heat pump
Complementarity principle (N. Bohr): The principle that a specified system can’t exhibit both wave-like behavior and particle-like behavior at similar time. That is, some experiments will reveal the wave-like nature of a system,
What is the appropriate formula employed to compute the acceleration? Explain in brief.
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
Define Hertz or SI unit of frequency: Hertz: Hz (after H. Hertz, 1857-1894): The derived SI unit of frequency, stated as a frequency of 1 cycle per s; it therefore has units of s-1.
Dielectric is a material in which energy can be accumulated. Ideally, it is a non-conductor of electric charge like insulators, but an efficient supporter of electrostatic fields. The
Superconductivity: The phenomenon by which, at adequately low temperatures, a conductor can conduct the charge with zero (0) resistance. The current theory for describing superconductivity is the BCS theory.
