How many vectors can be formed by joining the vertices of a given quadrilateral?
12 vectors, unless it is a parallelogram (13 if you include the null vector). If the quadrilateral is a parallelogram there will be two fewer.
What is the difference between parallelogram law of vector addition n triangle law of vector addition?
There is basically no difference. They are nothing more than 2 different visualizations of how we can graphically add two vectors.strictly if we say there is one and only difference is that---Triangle law of vector addition states that when 2 vectors r acting as the adjacent sides of a triangle taken in order. third side of the triangle will give the magnitude of th resultant 7 direction is in opposite order.Parallelogram law of vector addition states that if 2 vectors r acting as the adjacent sides of a parallelogram, then the diagonal of parallelogram from the point of intersection of two vectors represent their resultant magnitude & direction.
How do you use the parallelogram method to add more than two vectors?
Use the parallelogram method to add two of the vectors to create a single vector for them;Now use this vector with another of the vectors to be added (using the parallelogram method to create another vector).Repeat until all the vectors have been added.For example, if you have to add V1, V2, V3, V4 do:Used method to add V1 and V2 to result in R1Use method to add R1 and V3 to result in R2Use method to add R2 and V4 to give final resulting vector R.
Why you are using cosine function in dot product of two vectors?
It comes from the Law of Cosines. * * * * * For any two vectors A and B, the projection of A onto B, that is, the component of A along B, is ab.cos(x) where x is the angle between the two vectors. By symmetry, this is also the projectoin of B onto A.
Can the sum of two vectors be equal to either of the vectors explain?
Yes, if one of the vectors is the null vector.
What is parallelogram law of vectors?
"If two vector quantities are represented by two adjacent sides or a parallelogram then the diagonal of parallelogram will be equal to the resultant of these two vectors."
What is the parallelogram law of vectors?
"If two vector quantities are represented by two adjacent sides or a parallelogram then the diagonal of parallelogram will be equal to the resultant of these two vectors."
What is parallelogram law in physics?
whenever vectors act at the same time or from the same point.
What is Gravesand apparatus?
Gravesand apparatus is used to determine weight of body using parallelogram law of vectors.
What is parallelogram method?
parallelogram method is a common way of adding two vectors
Does law of vectors mean triangle law of vectors?
law of vectors also include the parallellogram law .
How many vectors can be formed by joining the vertices of a given quadrilateral?
12 vectors, unless it is a parallelogram (13 if you include the null vector). If the quadrilateral is a parallelogram there will be two fewer.
How are velocities in the same direction combined?
As the velocities are in the same direction then addition of vectors becomes so easy. We simply add the magnitudes of the velocities. If velocities go exactly opposite, then we get the difference of their magnitudes. If velocity vectors get inclined, then we use the parallelogram law of vectors to get the resultant.
How do you find the area of a parallelogram using 2 vectors?
Given two vectors a and b, the area of a parallelogram formed by these vectors is:a x b = a*b * sin(theta) where theta is the angle between a and b, and where x is the norm/length/magnitude of vector x.
What are the applications of Vectors?
vectors are the agents or vehciles which are helpfull in inserting forieng material in desired place

What does parallelogram law of forces state?
If two vectors, acting simultaneously at a point, can be represented both in magnitude and direction by the two adjacent sides of a parallelogram drawn from a point, then the resultant is represented completely, both in magnitude and direction by the diagonal of the parallelogram passing through the point.
