Lenght and direction
The unit vector is a vector whose magnitude is 1.
vector equal in magnitude and opposite direction
The (any) vector has 'direction' .
scalar has only a magnitude vector has both magnitude and direction
The resultant vector is the vector that 'results' from adding two or more vectors together. This vector will create some angle with the x -axis and this is the angle of the resultant vector.
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.
You will have to define what "accurately" means.
All components of the zero vector equal to zero.
The zero vector, denoted as 0, is a vector with all components equal to zero. It serves as the additive identity element in vector spaces, meaning that adding it to any vector does not change the vector's value.
linear transformation can be define as the vector of 1 function present in other vector are known as linear transformation.
It is a scalar quantity unless you define direction, then it becomes a vector quantity.
No. Raster images define images with pixels. But Vector images paint the pixels on your screen!
