WebAlthough a photon is massless, it still has momentum. Einstein's E = mc^2 formula is actually a special case of the special relativity formula E^2 = p^2c^2 + m^2c^4, where p is momentum, m is rest mass, E is energy, and c is the speed of light. If you substitute 0 for m (because a photon is massless), and E = hv (the formula for the energy of a ...

WebNov 12, 2014 · The mass of an electron is 9.11x10-31 kg, and the velocity is already given in km/s. You will need to convert the units of velocity into m/s (simply by multiplying by 10 3). You don't need to convert the units of the mass of the electron, since Joules is in (kg*m 2)/s 2 which, when simplified, will give you an answer for wavelength in meters. WebIn the classical model of a hydrogen atom, an electron orbits a proton with a kinetic energy of +13.6 eV and an electric potential energy of 27.2 eV. (a) Use the kinetic energy to calculate the classical orbital speed. (b) Use the electric potential energy to calculate the classical orbital radius.
WebSep 14, 2024 · To calculate the speed of an electron in an electric field, we use the following formula: v = \sqrt {\frac {2\cdot e\cdot V_ {\text {a}}} {m_ {\text {e}}}} v = me2 ⋅ e … WebDrift velocity is the average velocity with which, the electrons drift in the opposite direction of the field. We start with the acceleration of the electrons, a = F/m = eE/m. The average velocity gained, i.e. the drift velocity, due to this acceleration = a*t = eEt/m. Here, t = relaxation time, the time between two successive collisions.
WebMar 16, 2024 · The kinetic energy equation is as follows: KE = 0.5 × m × v², where: m – Mass; and. v – Velocity. With the kinetic energy formula, you can estimate how much energy is needed to move an object. The same energy could be used to decelerate the object, but keep in mind that velocity is squared.
