3 is.


How can parallel vectors be added together?

Just add their magnitudes. The combined vector will have the same direction as the original vectors.Just add their magnitudes.

Why a unit vector is aone type of vector but a vector is not a unit vector?

A unit vector is a vector whose magnitude is one. Vectors can have magnitudes that are bigger or smaller than one so they would not be unit vectors.


Two vectors have the length v1 is 3.5km and v2 is 4 kmwhat are the maximum and minimum magnitudes of their vector sum?

3.5+4.0 and 4.0-3.5


What is a minimum numbers of vectors to give zero resultant?

-- A singe vector with a magnitude of zero produces a zero resultant.-- Two vectors with equal magnitudes and opposite directions produce a zero resultant.


The vector sum of three vectors gives a resultant equal to zero What can you say about the vectors?

With three vectors spaced 120 degrees apart and with identical magnitudes the vector sum will be 0.


What is the angle between two vectors if their sum is to be maximum?

The resultant vector has maximum magnitude if the vectors act in concert. That is, if the angle between them is 0 radians (or degrees). The magnitude of the resultant is the sum of the magnitudes of the vectors.For two vectors, the resultant is a minimum if the vectors act in opposition, that is the angle between them is pi radians (180 degrees). In this case the resultant has a magnitude that is equal to the difference between the two vectors' magnitudes, and it acts in the direction of the larger vector.At all other angles, the resultant vector has intermediate magnitudes.


Can the magnitude of the resultant of two vector be greater than the sum of magnitudes of individual vectors?

No.


Can the magnitude of a resultant vector be greater than the sum of individual vectors?

The resultant vector IS the sum of the individual vectors. Its magnitudecan be the sum of their individual magnitudes or less, but not greater.


What is the minimum number of unequal vectors to result into a null-vector?

Two vectors; V1 + V2=0 where V1= -V2, two opposite vectors.


Can the sum of the magnitudes of two vectors ever b equal to the the sum of these two vectors?

Not really. The sum of the magnitudes is a scalar, not a vector - so they can't be equal. But the sum of the two vectors can have the same magnitude, if both vectors point in the same direction.


Explain what is meant by a concurrent vectors?

A vector has 2 components - it's magnitude and direction. Concurrent vectors are 2 vectors that have the same direction but may have different magnitudes.
