angle between three dimensional vectors

Dimensional formula - It is the term which tells about the power with which a fundamental quantity is contained in a physical quantity. E.g., Dimensional formula of velocity is [LT - 1 ], that of density is [ML - 3..

The bearing of a vector is the angle measured clockwise from the __ around to the vector. => North or South or West or East..

. In addition to this, the direction of the position vector gives the direction q in which P lies, as observed from 0. It is important to note that position vectors are different for different positions of the particle. The above explanation can be extended to a three dimen..

> The first case, that is, multiplication of a vector by a scalar has been dealt with in the section; multiplication of vectors by real numbers. Hence, we move on to the second case, that is, multiplication of two vectors in such a way as to yield a scalar. Such an ope..

Hexagonal close packing is the most efficient two dimensional close packing. Let us now consider a three dimensional packing keeping a hexagonal close packed pattern for layers. Two types of arrangements are possible. a) Hexagonal close packing - AB AB type of arrangement. b) C..

Imagine rotating a right handed screw whose axis is perpendicular to the plane formed by a and b so as to twist it from a to b through the angle p between the..

Identify the net for the 3-dimensional figure shown. => Figure 1 or Figure 2 or Figure 4 or Figure 3..

An example of resolution of a vector is the way a person walks. When a person walks, he/she presses the ground obliquely, (i.e., at an angle to the ground) in the backward direction. The ground offers an equal and opposite reaction in the opposite direction. The vertical compone..

Which of the following vectors have the opposite directions? =><3, 4>, <-3, -4> or <3, -4>, <-3, -4> or <3, 4>, <-3, 4> or <3, 4>, <3, -4>..
