Question

which option describes a vector quantity? (1 point)
○ it has magnitude, but no units or direction.
○ it has no magnitude, units, or direction.
○ it has magnitude, units, and direction.
○ it has magnitude and units, but no direction.

Explanation:

To determine the correct option for a vector quantity, recall the definition: a vector quantity is defined as a physical quantity that has both magnitude (a numerical value with units) and direction.

• The first option is incorrect because vectors have units and direction.
• The second option is incorrect as vectors do have magnitude, units, and direction.
• The third option matches the definition of a vector (magnitude, units, and direction).
• The fourth option describes a scalar quantity (which has magnitude and units but no direction), not a vector.

Answer:

C. It has magnitude, units, and direction.
