The total number of individual molecules in one mole of a substance, by definition equaling exactly 6.022 140 76 × 10 23. Avogadro's law A physical law which states that volumes of gases which are equal to each other at the same temperature and pressure will contain equal numbers of molecules. axion
Seating capacity differs from total capacity (sometimes called public capacity), which describes the total number of people who can fit in a venue or in a vehicle either sitting or standing. Where seating capacity is a legal requirement, however, as it is in movie theatres and on aircraft , the law reflects the fact that the number of people ...
Heat flow per unit time per unit surface area W/m 2: M T −3: Illuminance: E v: Wavelength-weighted luminous flux per unit surface area lux (lx = cd⋅sr/m 2) L −2 J: Impedance: Z: Resistance to an alternating current of a given frequency, including effect on phase ohm (Ω) L 2 M T −3 I −2: complex scalar Inductance: L
Particle density (particle count), number of particles per unit volume; Area-specific quantity, the quotient of a physical quantity and area ("per unit area"), also called areic quantities: [2] Current density, the ratio of electric current to area; Surface power density, power per unit area; Specific surface energy, free energy per unit ...
On the other hand, in situations where demand is strong for a product but the threat of cancellations rooms (e.g. hotel rooms or airline seats), firms often overbook in order to maximize revenue from full capacity. Overbooking's focus is increasing the total volume of sales in the presence of cancellations rather than optimizing customer mix. [4]
In the airline industry an available seat mile is the fundamental unit of production for a passenger-carrying airline. [2] A unit in this case is one seat, available for sale, flown one mile. For example, an aircraft with 300 seats available for sale flying 1,000 statute miles would generate 300,000 ASMs for that particular flight. That the ...
Mathematically, mass flux is defined as the limit =, where = = is the mass current (flow of mass m per unit time t) and A is the area through which the mass flows.. For mass flux as a vector j m, the surface integral of it over a surface S, followed by an integral over the time duration t 1 to t 2, gives the total amount of mass flowing through the surface in that time (t 2 − t 1): = ^.
Physics is the scientific study of matter, its fundamental constituents, its motion and behavior through space and time, and the related entities of energy and force. [1] Physics is one of the most fundamental scientific disciplines. [2] [3] [4] A scientist who specializes in the field of physics is called a physicist.
