Question

Which of the following statements is true?

• A. A scalar quantity is the one that is conserved in process.
• B. A scalar quantity is the one that can never take negative values.
• C. A scalar quantity is the one that does not vary from one point to another in space.
• D. A scalar quantity has the same value for observers with different orientation of the axes.

Answer 1

The correct option is D A scalar quantity has the same value for observers with different orientation of the axes.

Scalar quantity is defined only by its magnitude. Hence, it has the same value for observers with different orientations of the axes.
