The strong interaction, or strong nuclear force, is the most complicated interaction, mainly because of the way it varies with distance. The nuclear force is powerfully attractive between nucleons at distances of about 1 femtometre (fm, or 10 −15 metres), but it rapidly decreases to insignificance at distances beyond about 2.5 fm. At ...
In molecular physics and chemistry, the van der Waals force (sometimes van de Waals' force) is a distance-dependent interaction between atoms or molecules. Unlike ionic or covalent bonds, these attractions do not result from a chemical electronic bond; [2] they are comparatively weak and therefore more susceptible to disturbance.
Long-range penetration. A long-range penetration patrol, group, or force is a special operations unit capable of operating long distances behind enemy lines far away from direct contact with friendly forces as opposed to a Long Range Reconnaissance Patrol, a small group primarily engaged in scouting missions.
e. In nuclear physics and particle physics, the weak interaction, also called the weak force, is one of the four known fundamental interactions, with the others being electromagnetism, the strong interaction, and gravitation. It is the mechanism of interaction between subatomic particles that is responsible for the radioactive decay of atoms ...
A long-range reconnaissance patrol, or LRRP, is a small, well-armed reconnaissance team that patrols deep in enemy-held territory. [1] The concept of scouts dates back to the origins of warfare itself. However, in modern times these specialized units evolved from examples such as Rogers' Rangers in colonial British America, [1] the Lovat Scouts ...
One modern pioneer ballistic missile was the A-4, [1] commonly known as the V-2 developed by Nazi Germany in the 1930s and 1940s under the direction of Wernher von Braun. The first successful launch of a V-2 was on October 3, 1942, and it began operation on September 6, 1944, against Paris, followed by an attack on London two days later.
Nuclear physics. Force (as multiples of 10 000 N) between two nucleons as a function of distance as computed from the Reid potential (1968). [1] The spins of the neutron and proton are aligned, and they are in the S angular momentum state. The attractive (negative) force has a maximum at a distance of about 1 fm with a force of about 25 000 N ...
At the highest command level of a committed force or component (the division, corps, or field army-level), the force-level reconnaissance is employed to perform deep reconnaissance (or "long-range surveillance"), which is conducted beyond the force (or component) commander's area of influence to the limits of the area of interest (i.e. the ...
