it can be described in both. when graphically, it will be represented by an arrow in the direction of the vector and have the magnitude either written by it or you will have the arrow drawn to scale for the magnitude (length) of the arrow. numerically, you can break it down into its x, y, and z components and put them in from of i, j, and k respectively. ex a vector with x component of 3, y component of 2 and z component of 4 can be written as 3i +2j +4k

Can you graphically represent a vector which has magnitude but no direction?
If a quantity does not have a direction, its a scalar quantity, not a vector quantity.
What decscribes a vector?
A vector is a quantity described by size and direction. Mathematically, the square of a vector is negative, e.g. i^2 = -1, thus a quantity whose square is negative is a vector, e.g. 5i is a vector because (5i)^2 = -25.
If you are given the magnitude of a vector but no directionhow can you represent this vector graphically?
You cannot, unless it is a null vector. As a point.
Is momentum a vector quantity because it includes velocity which is also a vector quantity?
yes, momentum is a vector quantity.
Is length a scalar quantity or a vector quantity?
length is a scalar quantity buddy . but displacement is vector quantity. Length is a vector quantity If it is associated with direction.. Because having direction make it vector... S0 being vector or scalar depends upon how and where it is used..
