Scanning electron and transmission electron microscope
Give one benefit of a scanning electron microscope over the transmission electron microscope? Briefly explain it.
Expert
The SEM or scanning electron microscope has become more admired than the TEM or transmission electron microscope as it can generate images of high resolution, better clarity and three dimensional qualities and needs less sample preparation.

Avogadro's hypothesis (Count A. Avogadro; 1811): Equivalent volumes of all gases at similar temperature and pressure contain equivalent numbers of molecules. This is, in fact, true only for the ideal gases. <

Tachyon paradox: The argument explaining that tachyons (should they subsist, of course) can’t carry an electric charge. For an imaginary-massed particle travelling faster than c, less energy the tachyon has, the faster it travels, till at zero e
