In physics, an electronvolt is the measure of an amount of kinetic energy gained by a single electron accelerating from rest through an electric potential difference of one volt in vacuum. When used as a unit of energy, the numerical value of 1 eV in joules is equivalent to the numerical value of the charge of an electron in coulombs. Under the 2019 redefinition of the SI base units, this sets 1 eV equal to the exact value 1.602176634×10−19 J.
In physics, the kinetic energy of an object is the form of energy that it possesses due to its motion.
Voltage, also known as (electrical) potential difference, electric pressure, or electric tension is the difference in electric potential between two points. In a static electric field, it corresponds to the work needed per unit of charge to move a positive test charge from the first point to the second point. In the International System of Units (SI), the derived unit for voltage is the volt (V).
The molar gas constant is denoted by the symbol R or R. It is the molar equivalent to the Boltzmann constant, expressed in units of energy per temperature increment per amount of substance, rather than energy per temperature increment per particle. The constant is also a combination of the constants from Boyle's law, Charles's law, Avogadro's law, and Gay-Lussac's law. It is a physical constant that is featured in many fundamental equations in the physical sciences, such as the ideal gas law, the Arrhenius equation, and the Nernst equation.
Capacitance is the capability of a material object or device to store electric charge. It is measured by the charge in response to a difference in electric potential, expressed as the ratio of those quantities. Commonly recognized are two closely related notions of capacitance: self capacitance and mutual capacitance. An object that can be electrically charged exhibits self capacitance, for which the electric potential is measured between the object and ground. Mutual capacitance is measured between two components, and is particularly important in the operation of the capacitor, an elementary linear electronic component designed to add capacitance to an electric circuit.
A composite material is a material which is produced from two or more constituent materials. These constituent materials have notably dissimilar chemical or physical properties and are merged to create a material with properties unlike the individual elements. Within the finished structure, the individual elements remain separate and distinct, distinguishing composites from mixtures and solid solutions. Composite materials with more than one distinct layer are called composite laminates.
Inductance is the tendency of an electrical conductor to oppose a change in the electric current flowing through it. The electric current produces a magnetic field around the conductor. The magnetic field strength depends on the magnitude of the electric current, and follows any changes in the magnitude of the current. From Faraday's law of induction, any change in magnetic field through a circuit induces an electromotive force (EMF) (voltage) in the conductors, a process known as electromagnetic induction. This induced voltage created by the changing current has the effect of opposing the change in current. This is stated by Lenz's law, and the voltage is called back EMF.
Time dilation is the difference in elapsed time as measured by two clocks, either because of a relative velocity between them, or a difference in gravitational potential between their locations. When unspecified, "time dilation" usually refers to the effect due to velocity.
Whonamedit? is an online English-language dictionary of medical eponyms and the people associated with their identification. Though it is a dictionary, many eponyms and persons are presented in extensive articles with comprehensive bibliographies. The dictionary is hosted in Norway and was developed by medical historian Ole Daniel Enersen.
The Gambia Football Federation (GFF), formerly known as the Gambia Football Association, is the governing body of football in Gambia. It was founded in 1952, and affiliated to FIFA in 1968 and to CAF in 1966. It organizes the GFA League First Division, the GFA League Second Division and the national team. The current president is Lamin Kaba Bajo since September 2014.
Methorphan comes in two isomeric forms, each with differing pharmacology and effects:
Klistervatnet is a lake that lies on the border between Norway and Russia. The 17.2-square-kilometre (6.6 sq mi) lake lies on the river Pasvikelva and it is about 10 kilometres (6.2 mi) long and 2 kilometres (1.2 mi) wide. The lake is located north of lake Bjørnevatnet.
The Cagiva GP500 was a Grand Prix 500cc two-stroke motorcycle manufactured by Cagiva. It was released in various iterations throughout the years it was raced. Racing greats including Eddie Lawson, Randy Mamola, John Kocinski, Doug Chandler, Alex Barros and Mat Mladin, all raced versions of the GP500 at one time in their careers.
Coulomb's inverse-square law, or simply Coulomb's law, is an experimental law of physics that calculates the amount of force between two electrically charged particles at rest. This electric force is conventionally called the electrostatic force or Coulomb force. Although the law was known earlier, it was first published in 1785 by French physicist Charles-Augustin de Coulomb. Coulomb's law was essential to the development of the theory of electromagnetism and maybe even its starting point, as it allowed meaningful discussions of the amount of electric charge in a particle.
A dehestan is a type of administrative division of Iran. It is above the village and under the bakhsh. As of 2006, there were 2,400 dehestans in Iran.
In Turkey, time is given by UTC+03:00 year-round. This time is also called Turkey Time (TRT). The time at most is the same as in the Moscow Time and Arabia Standard Time zones. TRT was adopted by the Turkish Government on 8 September 2016. It was also in use in Northern Cyprus until it reverted to Eastern European Time (EET) in October 2017.
Colonia or Koloneia, also called Colonia in Armenia to distinguish it from other towns of the same name, was a town of ancient Lesser Armenia, inhabited during Hellenistic, Roman, and Byzantine times. It became important enough to be the seat of a bishop, a suffragan in the Late Roman Province of Armenia Prima, but faded like most in Asia Minor. No longer a residential bishopric, it remains, under the name Colonia in Armenia, a titular see of the Roman Catholic Church.
Campocraspedon is a genus of ichneumonid wasp in the insect order Hymenoptera. It comprises six species.
The single cylinder engine had been a mainstay of the Harley-Davidson line since the early days of the company's founding in 1903, but it was not until 1909 that the V-twin design was added. It was Introduced in 1926, and it disappeared from the program in 1934 and was reintroduced in 1937 as Harley-Davidson V - Twin B.
The COVID-19 vaccination campaign in Bosnia and Herzegovina is a mass immunization campaign that was put in place by the Bosnian authorities in order to respond to the ongoing COVID-19 pandemic. It started on 12 February 2021.
