Fluency Practice

A weather report states: "Wind speed is 25 mph." Is this a complete description of the wind as a vector quantity?

Yes — it gives the magnitude of the wind.

No — it gives speed (magnitude) but no direction; a vector requires both.

Yes — wind always blows in one direction, so direction is implied.

No — mph is not a valid unit for vectors.
