15. how do scalars and vectors differ? a) scalars have direction b) vectors have units c) scalars have units d) vectors have direction

Answer

Brief Explanations:

Scalars are quantities with only magnitude, while vectors have both magnitude and direction. Units can be associated with both scalars and vectors. Option a is incorrect as scalars have no direction. Option b is not the key - difference as both can have units. Option c is not the key - difference as units are not what differentiates them primarily. The main difference is that vectors have direction while scalars do not.

Answer:

D. vectors have direction
