A vector has (at minimum) how many parts associated with it?

1. Infinite
2. Two
3. One
4. Four
5. Five
6. Three

two (components along two axes.. or magnitude and direction angle)


Correct! A vector typically has two parts associated with it: magnitude and direction. Magnitude represents the length or size of the vector, while direction indicates the orientation or angle at which the vector points. So, option 2 is the correct answer.

To determine the components of a vector, you can use different coordinate systems such as Cartesian or polar coordinates. In Cartesian coordinates, the vector has two components along two perpendicular axes (typically x and y axes in 2D space or x, y, and z axes in 3D space). In polar coordinates, the vector's components are its magnitude and direction angle.
