The symbol most often used for density is ρ (the lower case Greek letter rho), although the Latin letter D can also be used. Mathematically, density is defined as mass divided by volume: [ 1 ] ρ = m V , {\displaystyle \rho ={\frac {m}{V}},} where ρ is the density, m is the mass, and V is the volume.
A, or a, is the first letter and the first vowel letter of the Latin alphabet, [1] [2] used in the modern English alphabet, and others worldwide.Its name in English is a (pronounced / ˈ eɪ / AY), plural aes.
The two values behave as equal in numerical comparisons, but some operations return different results for +0 and −0. For instance, 1/(−0) returns negative infinity, while 1/(+0) returns positive infinity (so that the identity 1/(1/±∞) = ±∞ is maintained).
An order of magnitude of time is usually a decimal prefix or decimal order-of-magnitude quantity together with a base unit of time, like a microsecond or a million years.In some cases, the order of magnitude may be implied (usually 1), like a "second" or "year".

If an isolated box of ideal mirrors could contain light, the individually massless photons would contribute to the total mass of the box by the amount equal to their energy divided by c 2. [7] For an observer in the rest frame, removing energy is the same as removing mass and the formula m = E / c 2 indicates how much mass is lost when energy ...
