Newtons laws of motion
Briefly illustrate all the Newton s laws of motion?
Expert
The Newton's laws of motion are as follows:
a) The body at rest will remain at rest and the body in motion will always remain in motion, until and unless acted on by the external force. (That is, Law of inertia)
b) The rate of change of momentum of a body is proportional to the resulting force acting on the body in similar direction as its motion. (That is, F = ma)
c) For all action there is an equal and opposite reaction.
What is the reason that the tea kettle sing? Briefly state the reason.
Laue pattern (M. von Laue): The pattern generated on a photographic film whenever high-frequency electromagnetic waves (like x-rays) are fired at the crystalline solid.
Schwarzschild radius: The radius ‘r’ of the event horizon for a Schwarzschild black hole of mass m is specified by (in geometrized units) r = 2 m. In its conventional units: r = 2 G m/c2
Kirchhoff's law of radiation (G.R. Kirchhoff): The emissivity of a body is equivalent to its absorbptance at similar temperature.
Planck radiation law: The law which explained blackbody radiation better than its precursor, therefore resolving the ultraviolet catastrophe. This is based on the supposition that electromagnetic radiation is quantized. Q : Describe the term ntu in thermodynamics Describe the term ntu in thermodynamics? Illustrate in short.

When air is compressed adiabatically the law connecting the absolute temperature T and the pressure P is of the form T = A.Pn where A and N are constants. Show by drawing a suitable linear graph that the experimental dat
As shown in the figure below, a source at S is sending out a spherical wave: E1=(A×D/r) cos(wt-2πr/λ); where r is the distance to source
What is Curie constant and Curies law? Curie constant: C (P. Curie): The characteristic constant, dependent on the material in question that points out the proportionality among its susceptibility
Hoop conjecture (K.S. Thorne, 1972): The conjecture (as so far unproven, although there is substantial proof to support it) that a non-spherical object, non-spherically compressed, will only form a black hole whenever all parts of the
