What items must be stated to specify to a vector quantity completely?
The vector magnitude and direction or the components of the vector.
What makes force a vector?
The fact that both a magnitude (number) and a direction is required to specify it.
What does it mean to say that momentum is a vector quantity and that energy is a scalar quantity?
In a vector quantity, it is important to specify a direction. In a scalar quantity, it isn't. Vectors (such as force) have a magnitude (size) and a direction (such as North). Scalars have only a magnitude.
How do two objects moving at the same speed have different velocities?
Velocity is a vector; to specify velocity, you indicate a speed (a magnitude), and a direction. If two objects move in different directions, their velocities will be different, even if their speeds are the same.Velocity is a vector; to specify velocity, you indicate a speed (a magnitude), and a direction.

What insulates better aluminum or plastic?
Plastic. In general, metals are good conductors, plastics are bad conductors. You didn't specify whether you wanted heat insulation or electrical insultation, but the above applies to both.
When probing the electric field direction it is necessary to specify that the magnitude of the test charge be very small?
A large "test charge" would influence the field you want to measure.

The vector magnitude and direction or the components of the vector.
Scalar and vector?
A scalar is a magnitude that doesn't specify a direction. A vector is a magnitude where the direction is important and is specified.
What is the suns absolute magnitude from earth?
You cannot ask for an absolute magnitude and specify the distance, as the absolute magnitude is derived from a set distance of 32.616 light years.At that distance, the absolute magnitude of the Sun is +4.83From Earth the apparent magnitude -26.74
What are Linear Units?
linear units only give the magnitude of a operand, they do not specify the direction
What makes force a vector?
The fact that both a magnitude (number) and a direction is required to specify it.
If you have multiple email servers how can you specify which of those is the primary email server?
By defining priorities in the MX record.
Three important parts of vector quantity?
To specify a vector, you need a length (or magnitude), and a direction.
Is it necessary to specify dimension while declaring an array?
yes
Why is it necessary to keep account?
Please specify the type of account you are referring to.
What is the advantages of using norms in an essay?
They specify the necessary conditions for your position.
What are the physical properties of machine oil?
It is necessary to specify the type of oil.
