This gun is a 1963 Auto 5. Value depends on condition. This is a Belgian gun and likely the 2nd barrel is a Japanese barrel with the invector chokes. Typically these guns in a "mixed" two barrel set / cased - run $1500-$2000. A mint 63 could bring more in the right market.
Still another velocity vector (or a zero vector).
You need to call Browning.
Given one vector a, any vector that satisfies a.b=0 is orthogonal to it. That is a set of vectors defining a plane orthogonal to the original vector.The set of vectors defines a plane to which the original vector a is the 'normal'.
another displacement
Any vector can be "decomposed" into components along any two non-parallel directions. In particular, a vector may be decomposed along a pair (more in higher dimensional spaces) of orthogonal directions. Orthogonal means at right angles and so you have the original vector split up into components that are at right angles to each other - for example, along the x-axis and the y-axis. These components are the rectangular components of the original vector. The reason for doing this is that vectors acting at right angles to one another do not affect one another.
The same as the original vector. The scalar will change the numbers, but not the dimensions.
Yes, in which case the resulting vector is twice the length of the original, pointing in the same direction.
100-500 USD depending on condition.
The vector quantity that indicates movement from one point to another is the velocity. The velocity is the rate of change of position and is a vector quantity.
The component of a vector x perpendicular to the vector y is x*y*sin(A) where A is the angle between the two vectors.
It is a vector that has the opposite direction to the reference positive direction. (A vector is one point in space relative to another.) Negative vector is the opposite direction
only if it is moved parallel to its original direction
