The semi-major axis ( major semiaxis) is the longest semidiameter or one half of the major axis, and thus runs from the centre, through a focus, and to the perimeter. The semi-minor axis ( minor semiaxis) of an ellipse or hyperbola is a line segment that is at right angles with the semi-major axis and has one end at the center of the conic ...
Axie Infinity is a blockchain game developed by Vietnamese studio Sky Mavis, [1] known for its in-game economy [2] which uses Ethereum-based cryptocurrencies. [3] It has been called 'a pyramid scheme that relies on cheap labor from countries like the Philippines to fuel its growth.' [ 4 ]
Counting efficiency varies for different isotopes, sample compositions and scintillation counters. Poor counting efficiency can be caused by an extremely low energy to light conversion rate, (scintillation efficiency) which, even optimally, will be a small value. It has been calculated that only some 4% of the energy from a β emission event is ...
In turn, radiative forcing is a scientific concept used to quantify and compare the external drivers of change to Earth's energy balance. [ 3 ] : 1–4 Radiative forcing is the change in energy flux in the atmosphere caused by natural or anthropogenic factors of climate change as measured in watts per meter squared.
Energy density. In physics, energy density is the amount of energy stored in a given system or region of space per unit volume. Often only the useful or extractable energy is measured. It is sometimes confused with stored energy per unit mass, which is called specific energy or gravimetric energy density .
Axle counter. An axle counter is a system used in railway signalling to detect the clear or occupied status of a section of track between two points. The system generally consists of a wheel sensor (one for each end of the section) and an evaluation unit for counting the axles of the train both into and out of the section.
Rotational energy or angular kinetic energy is kinetic energy due to the rotation of an object and is part of its total kinetic energy. Looking at rotational energy separately around an object's axis of rotation, the following dependence on the object's moment of inertia is observed: [ 1] where. The mechanical work required for or applied ...
In the Arrhenius model of reaction rates, activation energy is the minimum amount of energy that must be available to reactants for a chemical reaction to occur. [ 1] The activation energy ( Ea) of a reaction is measured in kilojoules per mole (kJ/mol) or kilocalories per mole (kcal/mol). [ 2] Activation energy can be thought of as the ...
