Define Lumen or SI unit of luminous flux
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.
Gaia hypothesis (J. Lovelock, 1969): The thought that the Earth as an entire must be regarded as a living organism and that biological procedures stabilize the atmosphere.
Briefly explain the measure of the force of gravity on the object?
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 : Define Stefan-Boltzmann constant Stefan-Boltzmann constant: sigma (Stefan, L. Boltzmann): The constant of proportionality exist in the Stefan-Boltzmann law. It is equivalent to 5.6697 x 10-8 W/m2/K4.
Stefan-Boltzmann constant: sigma (Stefan, L. Boltzmann): The constant of proportionality exist in the Stefan-Boltzmann law. It is equivalent to 5.6697 x 10-8 W/m2/K4.
Lumeniferous aether: The substance that filled all the vacant spaces between matter that was employed to elucidate what medium light was "waving" in. Now it has been harmed the reputation of, as Maxwell's equations entail that electromagnetic radiatio
The velocity of a body was observed to be constant throughout five minutes of its motion. Determine its acceleration during this interval?
