Is it possible to add three vector of equal magnitude but different directions to get a null vector?
Consider an equilateral triangle. If each vector started at the center of the triangle and went through a different vertex than the other two vectors then they would cancel. I believe in order for them to add to a null vector they must be co-planer.
Can two vectors having different magnitude be compined to give a zero resultant can three vector?
Two vectors, no; three vectors yes.
What is the proper notation used to express a point in the three-dimensional coordinate plane?
It is a three dimension vector : (x, y, z). It could be either a row vector or a column vector.
Can the magnitude of a vector be equal to one of its components?
Yes. A vector in two dimensions is broken into two components, a vector in three dimensions broken into three components, etc... If the value of all but one component of a vector equal zero then the magnitude of the vector is equal to the non-zero component.
What are the three different kinds of variable and describe each?
the three kinds of variables are independent,dependent and controlled
Is 3 blocks east a displacement?
Yes. A displacement is a vector. A vector is some sort of magnitude and a direction. Since 3 blocks is a magnitue(it is a distance) and east is a direction, the quantity is a vector, and therefore, a displacement. However, if you did not include a direction, the quantity is scalar, meaning it has magnitude, but no direction. Saying "Walk Three Blocks" could mean to walk three blocks in any direction. Not very useful. Hope this helps!
What is the resultant of two displacements?
The shortest distance from start to finish.
Three distinctly different psychodynamic defense mechanisms?
Denial, repression, displacement.
Why vector group is required?
There are various ways in which you can connect a three-phase transformer's primary and secondary windings, or in which you can connect three single-phase transformers to create a three-phase transformer bank. For example: wye-wye, wye-delta, delta-delta, delta-wye, etc.For each connection, there is a natural phase shift between the primary and secondary line voltages. This is called the angular displacement (or 'phase displacement') of the transformer connection.If you wish to parallel two three-phase transformers, or two three-phase transformer banks, then their angular displacements must be the same (there are also other requirements not relevant to this answer).A vector group is a method of specifying a three-phase transformer (or transformer bank) method of connection and its angular displacement. Transformer connections from the same group can be paralleled. Those in different groups cannot
How would you describe the different sources of electrical power?
Describe three different ICT sources.
What three terms describe different types of computers?
The three terms that describe different types of computers are size use processor speed.
Which are the three vectors that act along the mutually perpendicular direction?
cross product of tow vector result in a vector which is perpendicular the multiplying vector then these three vector are perpedicular

Can you add three unit vector to get a unit vector?
Yes.
Can two vectors having different magnitude be compined to give a zero resultant can three vector?
Two vectors, no; three vectors yes.
WHY DO POSITION IS A VECTOR QUANTITY?
To describe position, you need more than one number - for instance, an x-coordinate, a y-coordinate, and (if it is in three dimensions) a z-coordinate. That's the very essence of a vector - the fact that it is made up of several components.
What are the three different places on a bridge that would experience different forces?
describe three different places on a bridge that would experience very different forces
