Answer the following question given this paragraph: In physics, a quantity, such as mass, length, or speed that is completely specified by its magnitude and has no direction is called a scalar . A vector , on the other hand, is a quantity possessing both magnitude and direction. A vector quantity is typically represented by an arrow-tipped line segment. The length of the line, drawn to scale, represents the magnitude of the quantity. The direction of the arrow indicates the direction of the vector. Not only can vectors be represented graphically, but they can also be added graphically. Q: What do vectors possess that scalars do not? Choices: - height and polarity - direction and texture - magnitude and weight - magnitude and direction A:
A:
magnitude and direction
