- Which one is true for the triple product 17 - ? The result is a vector that might be parallel to A) The result is a vector that might be parallel to B) C) The result is a scalar O D) Such a product cannot be defined The result is a vector perpendicular to both E) A and BA vector has a magnitude of 2.8 m and points in a direction that is 135 counterclockwise from the a axis. You may want to review (Page 71).Can someone please help me understand this question and how to get the answer? Two displacement vectors have magnitudes of 5.0 m and 7.0 m, respectively. If these two vectors are added together, the magnitude of the sum is: 1.) equal to 8.6m 2.) could be as small as 2.0m or as large as 12.0m 3.)is equal to 2m 4. or is equal to 12m. Thank you. I am really confused.
