How will you multiply a vector by positive number?
A positive scalar multiplied by a vector, will only change the vector's magnitude, not the direction. A negative scalar multiplied by the vector will reverse the direction by 180°.
What is the number bi?
The answer depends on the context, but bi is a variable, not a number. It could be the ith of a set of variables b1, b2, ... .Or it could be the square root of -b2.Or it could be a vector of magnitude b in the idirection.
Is Photoshop a raster or vector based program?
raster
What is the differeance between Rasta and vector?
Raster images are defined in pixels. ie At every x,y location, whether it is black or white. Vector images are defined by lines. eg From x,y to X,Y. Any pixel that lies between these points on a white background becomes black. It is easier to convert Vector images to Raster images, rather than the other way. Vector images are sometimes smaller (in data size). eg If the image contains one line, then the amount of data needed to store this is smaller than having to define every pixel in the image regardless of whether it is relevant. Vector images can be scaled smaller and larger without any significant loss of detail. Raster images that have been made smaller lose clarity and cannot then be made larger to improve the quality.
A vector of magnitude 3 cannot be added to a vector of magnitude 4 so the magnitude of the resultant is?
7
How will you multiply a vector by positive number?
A positive scalar multiplied by a vector, will only change the vector's magnitude, not the direction. A negative scalar multiplied by the vector will reverse the direction by 180°.
What is meant by negative vector?
It is a vector that has the opposite direction to the reference positive direction. (A vector is one point in space relative to another.) Negative vector is the opposite direction
How can an object have negative momentum?
momentum is a vector quantity and therefore has direction. all vector quantities can have negative direction
What is the relationship between numbers and vectors discussing the displacement vector t and a negative?
A vector has a direction associated with it. A number (or scalar) does not.
What is different between negative vector and null vector?
A null vector has no magnitude, a negative vector does have a magnitude but it is in the direction opposite to that of the reference vector.
Can scalar be a negative number?
Yes, a scalar can be a negative number. For instance: c<x₁,x₂> = <cx₁,cx₂> such that <x₁,x₂> is a vector. Let c = -1 for instance. Then, we have this vector: <-x₁,-x₂> Compared to <x₁,x₂>, <-x₁,-x₂> has negative signs. In physics and mathematics, if we multiply the vector or something by a negative value scalar, then the direction of the vector is reversed, and the magnitude stays the same. If the magnitude increases/decreases, and the direction of the vector is reversed, then we can multiply the vector by any negative non-1 scalar value.
Can be magnitude of a vector have negative value?
Vectors have magnitude and direction. The magnitude is always a positive number.
Can the magnitude of a vector be negative?
No, the value can't be negative because magnitude of a vector is just how long it is regardless of its direction. :-)
What will be the change if a vector is multiplied by -2?
It will be twice as large as the original and have the opposite direction.
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...
Is displacement an example of vector quantity?
yes.... A2: displacement is for of a number where a vector has direction. Kind of the difference in speed and velocity but the main difference in this is velocity can be negative.
What is negative vector in physics?
That's a vector whose direction is exactly opposite to the direction that you designated as the positive one when the exercise or analysis began.
