F = N A / 1/e = 9.648 533 212 331 001 84 × 10 4 C⋅mol −1. One common use of the Faraday constant is in electrolysis calculations. One can divide the amount of charge (the current integrated over time) by the Faraday constant in order to find the chemical amount of a substance (in moles) that has been electrolyzed.
In the image, the vector F 1 is the force experienced by q 1, and the vector F 2 is the force experienced by q 2. When q 1 q 2 > 0 the forces are repulsive (as in the image) and when q 1 q 2 < 0 the forces are attractive (opposite to the image). The magnitude of the forces will always be equal.
Lorentz force F on a charged particle (of charge q) in motion (instantaneous velocity v). The E field and B field vary in space and time. The force F acting on a particle of electric charge q with instantaneous velocity v , due to an external electric field E and magnetic field B , is given by ( SI definition of quantities [ 1 ] ): [ 12 ]
Quantum efficiency (QE) is the fraction of photon flux that contributes to the photocurrent in a photodetector or a pixel. Quantum efficiency is one of the most important parameters used to evaluate the quality of a detector and is often called the spectral response to reflect its wavelength dependence.
The fates of Ohio State and Miami were the two major unknowns entering the College Football Playoff rankings that revealed the future of the field.

A Bronx-born mom, 42, Aviles-Ramos will get a whopping $414,799-a-year, a big jump from her last $232,754 Department of Education salary.
The Planck relation [1] [2] [3] (referred to as Planck's energy–frequency relation, [4] the Planck–Einstein relation, [5] Planck equation, [6] and Planck formula, [7] though the latter might also refer to Planck's law [8] [9]) is a fundamental equation in quantum mechanics which states that the energy E of a photon, known as photon energy, is proportional to its frequency ν: =.
