i have a huge test that i am trying to prepare for. However there are many problems about Vectors, which i do not get al all. i will give you just a few example of the different kinds of questions, if anyone know how to do any of these please help.. thanks a billion.
oh by the way this isn't my homework its just practice problems that i'd like to learn how to do before my test comes. thanks again.
1.A quantity with both a magnitude and a direction is called a
Scalar
Vector
Number
Unit
2. Vector A has a magnitude of 9 and points due north, vector B has a magnitude of 3 and points due north, and vector C has a magnitude of 5 and points due west. What is the magnitude of the resultant vector A+B+C?
20
13
15
11
3. The components of vectors are considered
Vectors
Scalars
