Question

what is a vector quantity? a quantity that only has magnitude a quantity that only has direction a quantity that has neither magnitude nor direction a quantity that has both magnitude and direction

Explanation:

A vector quantity is defined in physics as a quantity that has both magnitude (size) and direction. For example, velocity is a vector because it tells how fast an object is moving (magnitude) and in which direction. In contrast, a scalar (like speed) has only magnitude. The first option (only magnitude) describes a scalar. The second option (only direction) is incorrect as no physical quantity is defined this way. The third option (neither) is also wrong. The fourth option aligns with the vector definition.

Answer:

A quantity that has both magnitude and direction
