(a) A vector C of magnitude 7 lies along the x axis, and a vector D of magnitude 13 lies in the xy plane, 80 degrees from the x axis (see the figure). D (b) What is the magnitude and direction of the cross product C x D? magnitude C X DI = direction O +x O -x O ty O -y O + z O -z O in the xy plane, but not along the x or y axes O in the xz plane, but not along the x or z axes O in the yz plane, but not along the y or z axes What is the cross product D x C? D x C = (c) Draw both vectors on a diagram. (Do this on paper. Your instructor may ask you to turn in this work.)
