1. The problem statement, all variables and given/known data Which of the following are vectors? (Select all that apply.) a] ‹ 0.7, 0.7, -0.7 › b] ‹ 0, 2.3, -1 › c] 0 d] 5×‹ 33, 1.04, -9.5 › e] −3×10−6 f] 3.5 Which of the following are vectors? (Select all that apply.) a] a-> (the arrow is above the a) b] r->/2 c] |r->| d] 10r-> e] ‹ rx, ry, rz › f] r 2. Relevant equations A vector has a magnitude and direction. 3. The attempt at a solution I originally choose a and b because those are in the form that I'm familiar with...that of a position vector. However, this homework assignment is online and apparently those two are not correct. I then tried a,b, and d, since d (from what I can tell) is just a scalar multiplied by a vector...the answer of which is indeed a vector as well, but that wasn't right either. I think that c, e, and f are scalars. I really have no idea why the answers I gave are not correct, and would appreciate it if someone could shed some light on my errors. For the second problem, I thought that the answer would have been a and e. C is obviously the magnitude, and b & d are multiplied by a scalar. F is just a scalar, too. But as I decided in the first problem, multiplying a scalar by a vector just makes a vector. So I suppose I need to try a,b,d,and e? I'm feeling PRETTY dumb right now, since this is the homework after the first night. Encouragement as well as help would be greatly appreciated.
