Question

question a force is a vector quantity because it has select all that apply a reaction counterpart mass velocity an action counterpart direction magnitude

Explanation:

A vector quantity is defined as a quantity that has both magnitude (a numerical value) and direction. The other options relate to Newton's third law (action/reaction counterparts) or properties of matter (mass) or other vector quantities (velocity), which are not the defining characteristics of a vector itself.

Answer:

E. direction
F. magnitude
