In geometry and algebra, the triple product is a product of three 3-dimensional vectors, usually Euclidean vectors.The name "triple product" is used for two different products, the scalar-valued scalar triple product and, less often, the vector-valued vector triple product.
Scalar multiplication of a vector by a factor of 3 stretches the vector out. The scalar multiplications −a and 2a of a vector a. In mathematics, scalar multiplication is one of the basic operations defining a vector space in linear algebra [1] [2] [3] (or more generally, a module in abstract algebra [4] [5]).
In the natural sciences, a vector quantity (also known as a vector physical quantity, physical vector, or simply vector) is a vector-valued physical quantity. [9] [10] It is typically formulated as the product of a unit of measurement and a vector numerical value (), often a Euclidean vector with magnitude and direction.
[8] [9] In vector multiplication , there is a distinction between the cross and the dot symbols. The cross symbol generally denotes the taking a cross product of two vectors , yielding a vector as its result, while the dot denotes taking the dot product of two vectors, resulting in a scalar .
[9]: figs.7,8 Once the Poynting vector enters the conductor, it is bent to a direction that is almost perpendicular to the surface. [16]: 61 This is a consequence of Snell's law and the very slow speed of light inside a conductor. The definition and computation of the speed of light in a conductor can be given.
In linear algebra, a column vector with elements is an matrix [1] consisting of a single column of entries, for example, = [].. Similarly, a row vector is a matrix for some , consisting of a single row of entries, = […]. (Throughout this article, boldface is used for both row and column vectors.)
In physics and mechanics, torque is the rotational analogue of linear force. [1] It is also referred to as the moment of force (also abbreviated to moment).The symbol for torque is typically , the lowercase Greek letter tau.
In 2001 restructuring of Vektor by its parent company Denel, and a failed link up attempt with Colt USA led to the end production of civilian firearms by Vektor. As of July 2000, 13000 pistols had been sold, of which 6000 were sold outside of South Africa. [5] Because of the buy back program the pistols are now very rare in the United States.
