Total energy from the Sun that strikes the face of the Earth each second [189] 2.1×10 17 J: Yield of the Tsar Bomba, the most powerful nuclear weapon ever tested (50 megatons) [190] [191] 2.552×10 17 J Total energy of the 2022 Hunga Tonga–Hunga Haʻapai eruption [192] [193] 4.2×10 17 J: Yearly electricity consumption of Norway as of 2008 ...
In physics and chemistry, it is common to measure energy on the atomic scale in the non-SI, but convenient, units electronvolts (eV). 1 eV is equivalent to the kinetic energy acquired by an electron in passing through a potential difference of 1 volt in a vacuum. It is common to use the SI magnitude prefixes (e.g. milli-, mega- etc) with ...
The tonne (t) is an SI-compatible unit of mass equal to a megagram (Mg), or 10 3 kg. The unit is in common use for masses above about 10 3 kg and is often used with SI prefixes. For example, a gigagram ( Gg ) or 10 9 g is 10 3 tonnes, commonly called a kilotonne .
In analyzing these extreme events, Einstein's formula can be used with E as the energy released (removed), and m as the change in mass. In relativity, all the energy that moves with an object (i.e., the energy as measured in the object's rest frame) contributes to the total mass of the body, which measures how much it resists acceleration.
In the case of degenerate energy levels, we can write the partition function in terms of the contribution from energy levels (indexed by j) as follows: =, where g j is the degeneracy factor, or number of quantum states s that have the same energy level defined by E j = E s.
A percentage change is a way to express a change in a variable. It represents the relative change between the old value and the new one. [6]For example, if a house is worth $100,000 today and the year after its value goes up to $110,000, the percentage change of its value can be expressed as = = %.
In nuclear power technology, burnup is a measure of how much energy is extracted from a given amount of nuclear fuel [1].It may be measured as the fraction of fuel atoms that underwent fission in %FIMA (fissions per initial heavy metal atom) [2] or %FIFA (fissions per initial fissile atom) [3] as well as the actual energy released per mass of initial fuel in gigawatt-days/metric ton of heavy ...
TNT equivalent is a convention for expressing energy, typically used to describe the energy released in an explosion.The ton of TNT is a unit of energy defined by convention to be 4.184 gigajoules (1 gigacalorie), [1] which is the approximate energy released in the detonation of a metric ton (1,000 kilograms) of TNT.
