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.
What are the three different kinds of variable and describe each?
the three kinds of variables are independent,dependent and controlled
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 list that describe the three ways a displacement vector?
The three ways to describe a displacement vector are its magnitude (length), direction (angle or orientation), and starting and ending points in space. By specifying these three components, the full description of a displacement vector can be provided in three-dimensional space.
What is the resultant of two displacements?
The shortest distance from start to finish.
Is 3 blocks east a displacement?
Yes, moving 3 blocks east represents a displacement because it indicates a change in position from the starting point. Displacement is a vector quantity that measures the overall change in position regardless of the path taken.
How can you measure the magnitude of displacement of an object?
meters.
Three distinctly different psychodynamic defense mechanisms?
Denial, repression, displacement.
Are needed to describe a vector?
To describe a vector, you need both magnitude (size or length) and direction. In a 2D plane, this could be represented as an arrow with a certain length and direction. In a 3D space, it would require three coordinates to pinpoint its position and orientation.
How would you describe the different sources of electrical power?
Describe three different ICT sources.
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
What three terms describe different types of computers?
The three terms that describe different types of computers are size use processor speed.
Displacement can be used to find?
Displacement can be used to find the change in position of an object from its initial position to its final position. It is a vector quantity that includes both the magnitude and direction of the movement. It is often used in physics to analyze the motion of objects in one, two, or three dimensions.
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 you add three unit vector to get a unit vector?
Yes.
