Define Keplers 1-2-3 law
Kepler's 1-2-3 law: The other formulation of Kepler's third law, that relates to the mass m of the primary to a secondary's angular velocity omega and semi major axis a: m o = omega2 a3.

Give one benefit of a scanning electron microscope over the transmission electron microscope? Briefly explain it.
Gauss' law for magnetic fields (K.F. Gauss): The magnetic flux via a closed surface is zero (0); no magnetic charges present; in its differential form, div B = 0
Kirchhoff's law of radiation (G.R. Kirchhoff): The emissivity of a body is equivalent to its absorbptance at similar temperature.
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.
Lumen: lm: The derived SI unit of luminous flux, stated as the luminous flux produced by a uniform point source of 1 cd releasing its luminous energy over a solid angle of 1 sr; it therefore has units of cd sr.
Name the instrument which is used to measure the volume? Explain in short?
What do you mean by the term alloy? Briefly illustrate it.
What do you mean by the term neutral buoyancy? Briefly illustrate it.
Simultaneity principle: The principle which all frames of reference will contain invariant simultaneity; that is, the two events perceived as simultaneous (that is, containing the similar time coordinate) in one frame will be apparent as simultaneous
Brewster's law (D. Brewster) - The extent or level of the polarization of light reflected from a transparent surface is maximum whenever the reflected ray is at right angle to the refracted ray.
