Define Planck equation
Planck equation: The quantum mechanical equation associating to the energy of a photon E to its frequency nu: E = h nu.
Planck equation: The quantum mechanical equation associating to the energy of a photon E to its frequency nu:
E = h nu.
Describe when the intermolecular forces are strongest? Briefly state it.
Coanda effect: The effect which points out that a fluid tends to flow all along a surface, instead of flowing via free space.
Hubble constant: H0 (E.P. Hubble; 1925): The constant that determines the relationship among the distance to a galaxy and its velocity of recession due to the growth of the Universe. As the Universe is self-gravitating, it is not trut
What does MeV in MeV photon signify? Briefly describe it.
Mach's principle (E. Mach; c. 1870): The inertia of any specific particle or particles of matter is attributable to the interaction among that piece of matter and the rest of the world. Therefore, a body in isolation would contain no inertia.
Siemens: S (after E.W. von Siemens, 1816-1892): The derived SI unit of an electrical conductance equivalent to the conductance of an element which has a resistance of 1 O [ohm]; this has units of O-1.
Boltzmann constant: k (L. Boltzmann) - The constant that explains the relationship between kinetic energy and temperature for molecules in an ideal gas. This is equivalent to the 1.380 622 x 10-23 J/K.
Give one benefit of a scanning electron microscope over the transmission electron microscope? Briefly explain it.
Briefly illustrate how do fireworks turn to shapes similar to hearts and stars?
The voltage v mV in a circuit is given by: v = 20 sin (200 Πt - 0.7854) where t is the time in seconds (a) State the amplitude, frequency, period and phase angle of v.(b) Determine the initial voltage.(c) Determin
