Define Pseudoforce
Pseudoforce: The "force" that arises as an observer is plainly treating an accelerating frame as an inertial one.
Describe the universal law of universal gravitation? Briefly describe it.
Malus' law (E.L. Malus): The light intensity I of a ray with primary intensity I0 travelling via a polarizer at an angle theta among the polarization of the light ray and the polarization axis of the polarizer is specified by: Q : Scanning electron and transmission Give one benefit of a scanning electron microscope over the transmission electron microscope? Briefly explain it.
Give one benefit of a scanning electron microscope over the transmission electron microscope? Briefly explain it.
Standard quantum limit: It is the limit obligatory on standard techniques of measurement by the uncertainty principle in quantum mechanics.
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
Kirchhoff's law of radiation (G.R. Kirchhoff): The emissivity of a body is equivalent to its absorbptance at similar temperature.
Lux: lx: The derived SI unit of the illuminance equivalent to the illuminance generated by a luminous flux of 1 lm distributed consistently over a region of 1 m2; it therefore has units of lm/m2.
Briefly list out the name of all the branches of physics?
What do you mean by communication? Illustrate in brief.
Candela: The basic SI unit of luminous intensity stated as the luminous intensity in a given direction of a source which emits monochromatic photons of frequency 540 x 1012 Hz and encompasses a radiant intensity in the direction of 1/683 W/
