Einstein’s mass-energy relation See all related content special relativity, part of the wide-ranging physical theory ofrelativityformed by the German-born physicistAlbert Einstein. It wasconceivedby Einstein in 1905. Along withquantum mechanics, relativity is central to modernphysics. ...
to its molar mass(m). mole ideal gas constant r physical constant relates the average kinetic energy of an ideal gas with temperature. it is expressed in units of energy per temperature increment per mole 8.3144598(48) j.k -1 .mol -1 temperature t measure of heat k or 0 c what is ...
Note that if the microscopic density of the α-phase is constant, the intrinsic phase average will be equal to the mass average, i.e., (A.10)<f>αα=f̃α.This is an important property which is used in the derivation of the macroscopic equations. A.2 Spatial averaging theorem The ...
whereRis theuniversal gas constant(8.3 joules per degree Celsius per mole) andMis the molar mass, or an average molar mass if the gas is a mixture; for air, theappropriateaverage is about 29 × 10−3kilogram per mole. For other fluids knowledge of the equation of state is often incompl...
From the last equation, it is possible to find i: i =2/(γ –1). Rewrite the adiabatic equation and find γ: p2p1=(V1V2)γ,therefore, i=2lnp2p1lnV1V2-1=2ln(V1V2)lnp2V2P1V1.Execute calculations and arrive at: i = 4.99 ≈ 5.0. This means that the gas is biatomic. (2)...
For this purpose, we have made use of the latest experimental atomic mass data complemented with a Hartree-Fock-Bogoliubov (HFB) mass model. Magnetar crusts are found to be significantly different from the crusts of ordinary neutron stars.

Accordingly, we find Euler and D'Alembert devoting their talent and their patience to the establishment of the laws of rotation of the solid bodies. Lagrange has incorporated his own analysis of the problem with his general treatment of mechanics, and since his time M. Poinsôt has brought ...
half of it to decay; it makes little sense to talk about the half-life of a single atom, for instance. But this measure is useful because it is not possible to determine exactly which nucleus will decay and when – the process can only be understood statistically, on average, over time...
