2'. What value of 0 corresponds to a vector that is horizontal? 8. What value of El corresponds to a vector that is vertical":I Activity 2: Graphical Repraentation of a Vector Through Cartesian and Polar Coordinata A vector a can be described either by the cartesian coordinates Elva, or by the polar coordinates 21,3 9.
