When are vectors said to be perpendicular?
Perpendicular means that the angle between the two vectors is 90 degrees - a right angle. If you have the vectors as components, just take the dot product - if the dot product is zero, that means either that the vectors are perpendicular, or that one of the vectors has a magnitude of zero.
When are two vectors identical?
Two vectors are identical when all their components are identical. An alternative definition, for vectors used in physics, is that they are identical when both the magnitude and the direction are identical.
Can the directions of the sum of two two vectors be equal to the directions of difference of two vectors?
Yes.
Are all unit vectors equal?
No. Their magnitudes are equal (that's why they're "unit" vectors), but their directions are different.
Applications of vectors?
vectors help in determining the direction . they give the magnitude of the number as well as the direction of the quantity
How do you add two null vectors by following vector laws of addition?
The sum of two null vectors is a null vector. And since a direction is not relevant for a null vector, the resultant has no direction either.
What is the sum of to vectors?
A variety of mathematical operations can be performed with and upon vectors. One such operation is the addition of vectors. Two vectors can be added together to determine the result (or resultant). This process of adding two or more vectors has already been discussed in an earlier unit. Recall in our discussion of Newton's laws of motion, that the net force experienced by an object was determined by computing the vector sum of all the individual forces acting upon that object. That is the net force was the result (or resultant) of adding up all the force vectors. During that unit, the rules for summing vectors (such as force vectors) were kept relatively simple. Observe the following summations of two force vectors:
What is the difference between vectors and non-vectors?
Coplanar :The vectors are in the same plane.Non coplanar :The vectors are not in the same plane.
When adding vectors in one dimension which the following could the length of the arrows represent?
The length of the arrows could represent either the magnitude or the direction of the vectors. If the length represents magnitude, longer arrows would represent larger magnitudes of the vectors. If the length represents direction, the arrows would be all the same length, but pointing in different directions to represent different vectors.
What is arthropod vectors?
Vectors of the arthropod.
What are the types of vectors are there in biotechnology?
there are two types of vectors cloning vector and expression vectors.
Can two vectors having different magnitudes be combined to give a zero resultant can three vectors?
Two vectors: no. Three vectors: yes.
Can velocity vectors be combined with force vectors?
No
What are the coplanar vectors in mathematics?
Vectors that sum to zero are coplanar and coplanar vectors sum to zero.
Is it possible to combine two vectors of different magnitude to give a zero resultant if not can three vectors be combine?
Two vectors: no. Three vectors: yes.
What is the difference between orthogonal and orthonormal vectors?
All vectors that are perpendicular (their dot product is zero) are orthogonal vectors.Orthonormal vectors are orthogonal unit vectors. Vectors are only orthonormal if they are both perpendicular have have a length of 1.
Does law of vectors mean triangle law of vectors?
law of vectors also include the parallellogram law .
