The RC time constant, denoted τ (lowercase tau ), the time constant (in seconds) of a resistor–capacitor circuit (RC circuit), is equal to the product of the circuit resistance (in ohms) and the circuit capacitance (in farads ), i.e.: It is the time required to charge the capacitor, through the resistor, from an initial charge voltage of ...
In electromagnetism, current density is the amount of charge per unit time that flows through a unit area of a chosen cross section. [1] The current density vector is defined as a vector whose magnitude is the electric current per cross-sectional area at a given point in space, its direction being that of the motion of the positive charges at ...
30 mm caliber. The 30 mm caliber is a range of autocannon ammunition. It includes the NATO standardized Swiss 30×173mm (STANAG 4624), the Soviet 30×155mmB, 30×165mm and 30×210mmB, the Czechoslovak 30×210mm, the Yugoslav 30×192mm, the British 30×113mmB, and the French 30×150mmB and 30×170mm cartridges.
One terahertz is 10 12 Hz or 1,000 GHz. Wavelengths of radiation in the terahertz band correspondingly range from 1 mm to 0.1 mm = 100 μm. Because terahertz radiation begins at a wavelength of around 1 millimeter and proceeds into shorter wavelengths, it is sometimes known as the submillimeter band, and its radiation as submillimeter waves ...
Effective firing range. 2,000 m (1.2 mi) effective. Maximum firing range. 3,000 m (1.9 mi) VENOM LR is an autocannon derived from ADEN 30 mm gun, although most of its components and working principle being different. The LR stands for low recoil. It is designed to be fired from RCWS that can mount 12.7 mm machinegun. [1]
Stopping power. Stopping power is the ability of a weapon – typically a ranged weapon such as a firearm – to cause a target (human or animal) to be incapacitated or immobilized. Stopping power contrasts with lethality in that it pertains only to a weapon's ability to make the target cease action, regardless of whether or not death ...
The femtometre (American spelling femtometer ), symbol fm, [1] [2] [3] (derived from the Danish and Norwegian word femten 'fifteen', Ancient Greek: μέτρον, romanized : metrοn, lit. 'unit of measurement') is a unit of length in the International System of Units (SI) equal to 10 −15 metres, which means a quadrillionth of one metre.
Manual 3-round clip. The L21A1 RARDEN ("Royal Armament, Research and Development Establishment" and "Enfield") is a British 30 mm autocannon used as a combat vehicle weapon. [1] The Royal Armament Research and Development Establishment (RARDE) and the Royal Small Arms Factory (RSAF), were part of the Ministry of Defence, at the time.
