The elementary charge e, i.e. the negative charge on a single electron or the positive charge on a single proton: 10 −18: atto-(aC) ~ 1.8755 × 10 −18 C: Planck charge: 10 −17: 1.473 × 10 −17 C (92 e) – Positive charge on a uranium nucleus (derived: 92 x 1.602 × 10 −19 C) 10 −16: 1.344 × 10 −16 C: Charge on a dust particle in ...
Radiation exposure is a measure of the ionization of air due to ionizing radiation from photons. [1] It is defined as the electric charge freed by such radiation in a specified volume of air divided by the mass of that air. [1] As of 2007, "medical radiation exposure" was defined by the International Commission on Radiological Protection as ...
U.S. Open pool championships and U.S. Open pocket billiards championships are generic terms that may refer to various professional pool tournaments, not all of them affiliated with each other. "U.S. Open Pocket Billiards Championship" as a proper noun most often refers to the straight pool (14.1 continuous pool) championship, the oldest of the ...
Electromagnetism. In special and general relativity, the four-current (technically the four-current density) [1] is the four-dimensional analogue of the current density, with units of charge per unit time per unit area. Also known as vector current, it is used in the geometric context of four-dimensional spacetime, rather than separating time ...
Anode ray. Anode ray tube showing the rays passing through the perforated cathode and causing the pink glow above it. An anode ray (also positive ray or canal ray) is a beam of positive ions that is created by certain types of gas-discharge tubes. They were first observed in Crookes tubes during experiments by the German scientist Eugen ...
Pool suction drain injury, also known as suction entrapment, occurs when the drain of a wading pool, swimming pool, hot tub, or fountain sucks in a swimmer's jewelry, torso, limbs, hair or buttocks. In some cases of buttocks entrapment, victims are disemboweled. In the United States, 147 incidents were documented between 1985 and 2002 of which ...
The injury forced Rahm to withdraw from the LIV Golf event in Houston this past weekend, eliciting concerns about his ability to compete in this week's U.S. Open. "I don't know how or what ...
Partial charge. In atomic physics, a partial charge (or net atomic charge) is a non- integer charge value when measured in elementary charge units. It is represented by the Greek lowercase delta (𝛿), namely 𝛿− or 𝛿+. Partial charges are created due to the asymmetric distribution of electrons in chemical bonds.
