Rest mass energy of the electron
What do you mean by the rest mass energy of the electron?
Expert
According to the Einstein's Theory of Relativity, the mass of a body (state a particle) based on the energy and on the momentum (say velocity) with which the particle moves.
Now, we have a problem: Is there a mass value which every observer can relate to? Yes: it is the rest mass that is the mass you could measure in the frame of reference co-moving with the particle (in which the particle is still), that is the center of mass frame and which coincide with the minimum value measurable for each and every observers.
Rayleigh-Jeans law: For a blackbody at the thermodynamic temperature T, the radiance R over a range of frequencies between the nu and nu + dnu is specified by: R = 2 pi nu2 k T/c2.<
The velocity of a body was observed to be constant throughout five minutes of its motion. Determine its acceleration during this interval?
No-hair conjecture (1960s): The conjecture (confirmed in the 1970s and 1980s) in general relativity that a black hole has merely three salient external characteristics: angular momentum, mass, and electric charge. All the other proper
Huygens' construction: Huygens ‘Principle (C. Huygens): The mechanical propagation of the wave (specially, of light) is equal to supposing that every point on the wave front acts as a point source of the wave emission.
A dual-wavelength spectrometer uses 780 nm and 830 nm. The molar extinction coefficients for oxy-hemoglobin (HbO2) and deoxy-hemoglobin (Hb) at these two wavelengths are: e_HbO2_780nm = 710 cm-1M-1, e_Hb_780nm = 1075 cm
