part 1 of 1 it) points 'When two vectors sum to zero, how must, they be related? 1. The magnitudes are different; the direc- tions are the same. 2. The magnitudes are the same; the direc tions are opposite. 3. The magnitudes are the same; the direc- tions are the same. 4. The magnitudes are different; the direc tions are opposite. 5. All are wrong. ______________-- Question 7 part 1 of 1 10 points _ Consider three force vectors F1, F2, and F3. The vector F1 has magnitude F1 2 43 N and direction 61 = 49 ; the vector F2 has magnitude F2 : 39 N and direction 62 = 140 ; and the vector 133 has magnitude F3 = 27 N and direction 03 : 49 . All the direction angles 0 are measured from the positive 1' axis: counterclockwise for 9 > 0 and clockwise for 6
