I need help with these 4 questions quickly, no explanation needed!!!

Question 1 (1 point) For which of the following conditions will the cross product of two vectors be zero? a) If the angle between them is 90. b) if the angle between them is 0. O c) If the angle between them is 450. O d) if the vectors have the same magnitude. Question 2 (1 point) Given la] = 12 cm, lb| = 13 cm, and the angle between the two vectors, when placed tail to tail, is 350. Find la x bl . a) la x bl = 156 b) la x bl = 89 c 12 x bl = 6 Od) la x b/ = 128 Question 3 (1 point) 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. Question 4 (1 point) What is (0, 0, 1) x (0, 1, 0)? a (-1, 0, 0,) b) (1, 0, 0) c (0, 0, 1) d) (0, -1, 0)
