Final answer:
The angle between the x and y components of a vector is 90°.
Step-by-step explanation:
The angle between the x and y components of a vector is 90° (option a). This can be explained using trigonometry.
When a vector is represented by its x and y components, it forms a right triangle with the x-axis and y-axis. The angle between the vector and the x-axis is the same as the angle between the vector and the y-axis. In a right triangle, the angle opposite the hypotenuse is always 90°. Therefore, the angle between the x and y components is 90°.
