1 (a) State what is meant by a scalar quantity and by a vector quantity.scalar:..■vector:…[2](b)Complete Fig. 1.1 to indicate whether each of the quantities is a vector or a scalar.quantity vector or scalar power temperature momentum Fig.1.1[2](c)An aircraft is travelling in wind...
displacement, momentum, and so on. Now, coming to vector multiplication which is one of the geometric properties of vectors, there are two ways to find the product. One is the cross product and the other one is the dot product. These...
We consider an N× N random vector x with joint pdf fx(x) with support X. Then we have a set of regions Cl in X that decompose this vector space in a mutually exclusive and collectively exhaustive manner—i.e., X=∪l=1LClandCl∩Cm=ϕ,for all l≠m, where ϕ is the ...

Scalar quantitieshave a size or magnitude only and need no other information to specify them. Thus, 10 cm, 50 sec, 7 litres and 3 kg are all examples of scalar quantities. Vector quantities have both a size or magnitude and a direction, called the line of action of the quantity. ...
The value of the vector triple product can be found by the cross product of a vector with the cross product of the other two vectors. Vector triple products arise in the discussion of rotational motion, and generally, it is used to simplify the different vector formulas. ...
- |B| is the magnitude of vector B,- θ is the angle between the two vectors. Step 2: Analyze the MagnitudesThe magnitudes |A| and |B| are always non-negative (i.e., they are either positive or zero). Therefore, the product of the magnitudes |A||B| is also non-negative. Step...
