Explain Pascals principle
Pascal's principle: The pressure exerted to an enclosed incompressible static fluid is transmitted undiminished to all portions of the fluid.
Explain what does held the nucleons altogether in a nucleus?
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.
Assuming that ground stations are equally distributed on the Earth, how many ground stations are required to maintain constant contact with a spacecraft at 750 km altitude, and 72 degrees inclination?
What do you mean by the rest mass energy of the electron?
Tesla: T (after N. Tesla, 1870-1943): The derived SI unit of the magnetic flux density stated as the magnetic flux density of a magnetic flux of 1 Wb via an area of 1 m2; it therefore has units of Wb/m2.
Rayleigh criterion: resolving power: The criterion for determining how delicately a set of optics might be able to differentiate. This starts with the supposition that central ring of one image must fall on the first dark ring of the other; for
Rayleigh-Jeans law: For a blackbody at the thermodynamic temperature T, the radiance R over a range of frequencies between the nu and nu + dnu is specified by: R = 2 pi nu2 k T/c2.<
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,
Briefly list out the name of all the branches of physics?
Landauer's principle: The principle which defines that it doesn't explicitly take energy to calculate data, however instead it takes energy to remove any data, as erasure is a vital step in computation.
