Question

O a If the angle between them is 90 b If the angle between them is 0 c If the angle between them is 45 d If the vectors have the same magnitude If a 2 6 6 and b 3 2 7 find a b Your Answer Answer Which statement best describes the result of the cross product a It gives the magnitude of the projection of one vector onto another b It defines a vector perpendicular to both given vectors c The cross product gives a vector parallel to both given vectors O d It is the division of one vector by another If A 3 2 9 and B 4 7 2 are two points in 3 space then find the vector AB a b AB 7 5 71 d AB 1 9 11 1 AB 1 12 14 18 AB 17 5 71 The dot product represents a The magnitude of the projection of one vector onto another b A vector perpendicular to both given vectors c A vector parallel to both given vectors d The division of one vector by another Ifp 7 2 5 1 q a P q 112 3 b P q 12 1 find find p q
