I just wanted to make sure I'm doing my homework correctly, please let me know if any of the following is incorrect, if anyone knows. most the questions are multiple choice but im just posting what I found to be the answer. thanks,: 1- What type of quantity is characterized by both magnitude and direction? Vector 2- When we add a displacement vector to another displacment vector, the result is: a displacement vector 3- A student adds two vectors. One has a magnitude of 200 and the other has a magnitude of 40. Which of the following is the only possible chice for the magnitude of the resultant? ok, so im assuming the vectors are at a right angle so I used the phthalgorym therom or whatever (A squared + B squared = C squared) and I came out with 204, and one of my choices was 200 (the other choices were 100,260, and 40) Im just a little scetchy on this answer and wondering if I should have gone about it a different way. Any input is greatly appreciated. Thanks.
