Question
A situation may be described by using different sets of coordinate axes having different orientations. Which of the following do not depend on the orientation of the axes?
  1. The value of a scalar.
  2. Component of a vector.
  3. A vector.
  4. The magnitude of a vector.

Answer

  1. The value of a scalar.

  1. A vector.

  2. The magnitude of a vector.

Explanation:

The value of a scalar, a vector and the magnitude of a vector do not depend on a given set of coordinate axes with different orientation. However, components of a vector depend on the orientation of the axes.
