Three important parts of vector quantity?
To specify a vector, you need a length (or magnitude), and a direction.
How do you do cross products?
You need to know that the cross product of two vectors is a vector perpendicular to both vectors. It is defined only in 3 space. The formula to find the cross product of vector a (vector a=[a1,a2,a3]) and vector b (vector b=[b1,b2,b3]) is: vector a x vector b = [a2b3-a3b2,a3b1-a1b3,a1b2-a2b1]
Can a vector be represented in terms of unit vector?
Yes, a vector can be represented in terms of a unit vector which is in the same direction as the vector. it will be the unit vector in the direction of the vector times the magnitude of the vector.
How to find the direction of vector when the magnitude is given?
You can't derive the direction only from the magnitude. A vector with the same magnitude can have different directions. You need some additional information to make conclusions about the direction.You can't derive the direction only from the magnitude. A vector with the same magnitude can have different directions.

Is vector A parallel vector B given that vector A is equal to the zero vector and vector B is equal to the zero vector?
The zero vector is both parallel and perpendicular to any other vector. V.0 = 0 means zero vector is perpendicular to V and Vx0 = 0 means zero vector is parallel to V.
Is direction a vector?
"North" is a valid direction, but for a vector, you would also need a magnitude.

What info do you need to define vector quantity?
To define a vector quantity, you need to specify both its magnitude (size) and its direction in space. This is essential in distinguishing vector quantities from scalar quantities, which only have magnitude.Vectors can also be expressed in terms of their components along each coordinate axis.
What two quantities are neccesarz to determine a vector quantities?
To determine a vector quantity, you need both magnitude (size or length of the vector) and direction. These two quantities are essential for describing a vector completely in a given reference frame.
What is need of space vector pulse width modulation?
due to space vector modulation we can eliminate the lower order harmonics

Why vector division is not possible?
In the case of the dot product, you would need to find a vector which, multiplied by another vector, gives a certain real number. This vector is not uniquely defined; several different vectors could be used to give the same result, even if the other vector is specified. For the other two common multiplications defined for vector, the inverse of multiplication, i.e. the division, can be clearly defined.
How do you prove that weight is a vector quantity?
You don't need to prove much - just look at the definition of a vector. A vector includes a magnitude (in this case the force), and a direction. Since weight (or "the force of gravity") is directed to a certain direction, namely downward, you can consider it a vector.You don't need to prove much - just look at the definition of a vector.

Is north a vector direction?
Yes, north is a vector direction because it has both magnitude (distance) and direction. It is typically represented by an arrow pointing upwards on a map.
Why is electricity scalar not vector?
i also need the answer can anybody tell me too
What two pieces of information are necessary in order to define vector quantity?
To define a vector quantity, you need both magnitude (the numerical value) and direction. This combination of magnitude and direction is what distinguishes vector quantities from scalar quantities, which only have magnitude.
Will a vector be zero if one of its compoent is zero?
No. In order for the magnitude of a vector to be zero, the magnitude of all of its components will need to be zero.This answer ignores velocity and considers only the various N-axis projections of a vector. This is because direction is moot if magnitude is zero.
