Define Kirkwood gaps
Kirkwood gaps (Kirkwood): The gaps in the asteroid belt, caused by the resonance effects from Jupiter. Similar gaps are also exists in Saturn's rings, due to the resonance effects of the shepherd moons.
A thermocouple of K type is suddenly exposed to air with temperature of 1273K, Initial temperature was 293 K. Calculate the time needed for the thermocouple read the temperature with accuracy of better that 99%. Ignore radiation and conduction. The measuring element has a ball shape of diameter o
Coanda effect: The effect which points out that a fluid tends to flow all along a surface, instead of flowing via free space.
Explain Keplers laws or Keplers first law, second law and third law? Kepler's laws (J. Kepler) Kepler's first
Standard quantum limit: It is the limit obligatory on standard techniques of measurement by the uncertainty principle in quantum mechanics.
How do I find out a maximum current flowing through a resistor with just the resistance of the resistor and it's power rating?
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/
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.
Trojan points: L4 and L5 are the two dynamically stable Lagrange points (that is, beneath certain conditions).
Fermat's principle: principle of least time (P. de Fermat): The principle, put onward by P. de Fermat that explains the path taken by a ray of light among any two points in a system is for all time the path which takes the least time.
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
