What is Gray
Gray: Gy (after L.H. Gray, 1905-1965): The derived SI unit of engrossed dose, stated as the absorbed dose in which the energy per unit mass communicated to the matter by the ionizing radiation is 1 J/kg; it therefore has units of J/kg.
Describe the reason in short why the length of a standard meter re-defined in the year of 1983?
What do you mean by the rest mass energy of the electron?
Explain how asteroids are formed? Describe.
What is the appropriate formula employed to compute the acceleration? Explain in brief.
Write down the vital difference between the electron and a beta ray?
Pfund series: The series that explains the emission spectrum of hydrogen whenever the electron is jumping to the fifth orbital. Each line is in the infrared part of the spectrum.
Geometrized units: The system of units whereby certain basic constants (G, c, k, and h) are set to unison. This makes computations in certain theories, like general relativity, much simpler to deal with, as such constants appear often. Q : Define Pseudoforce Pseudoforce : The Pseudoforce: The "force" that arises as an observer is plainly treating an accelerating frame as an inertial one.
Pseudoforce: The "force" that arises as an observer is plainly treating an accelerating frame as an inertial one.
Newton's law of universal gravitation (Sir I. Newton): Two bodies exert a pull on each other with equivalent and opposite forces; the magnitude of this force is proportional to the product result of the two masses and is too proportional to the invers
Planck constant: h: The basic constant equivalent to the ratio of the energy of a quantum of energy to its frequency. This is the quantum of action. This has the value 6.626 196 x 10-34 J s.
