It means that the direction of the vector is that same as before but the magnitude has been changed - by a scalar factor.

What is null vector?
NULL VECTOR::::null vector is avector of zero magnitude and arbitrary direction the sum of a vector and its negative vector is a null vector...
What is a unit vector?
It is a vector whose magnitude is 1.It is a vector whose magnitude is 1.It is a vector whose magnitude is 1.It is a vector whose magnitude is 1.
What is the opposite to vector addition?
the opposite to vector addition is vector subtraction.
What are vector components?
prrpendicular projections of a vector called component of vector
Define the unit vector?
The unit vector is a vector whose magnitude is 1.
Difference between Vector graphics and roster graphics?
Raster graphics are stored as pixels, vector graphics are stored as geometric primitives. Images of the latter type can, in principle, be scaled infinitely, and pixelization will not occur.
Which of these references a velocity (not speed)?
I would say vector
What is the difference between vector and rester?
Main difference is that you can enlarge vector graphics without lose of quality. Vector graphics can be scaled and changed at any time without any lose of quality or appearance while raster images can lose sharpness and quality when you scale or change them.
How did romeo get in juliets place what does he say?

Is mosquito a vector?
I would say yes, as it can carries Malaria.
Where is the resultant vector lies when dot product of two vector is done?
arithmetic mean
What does the word scalle mean on the back of a piece of 14kt jewelry?
it was scaled in weight.
Can a fence be scaled?
Nope it can not be scaled
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.
What can you say about two vectors if vector A vector B 0?
Depends on the situation. Vector A x Vector B= 0 when the sine of the angle between them is 0 Vector A . Vector B= 0 when the cosine of the angle between them is 0 Vector A + Vector B= 0 when Vectors A and B have equal magnitude but opposite direction.
Can you use scalar mean wind speed with vector mean wind direction?
Why would wind direction be a vector? These quantities should be the same size. You could combine them into wind velocity, which would be a vector.
What does vector mean in science terms?
Any physical quantity which has both direction and magnitude is called a vector. A quantity must also obey the 'Triangle law of vector addition' to be called as a vector. For example displacement is a vector, u can say a person moved 5 km (magnitude) along west(direction). But electric current is not a vector, it has magnitude and its direction is from +ve terminal to -ve terminal but it doesn't obey triangle law. Rather currents are added as scalars.
