Question
Which one of the following statements is true?
Options
A scalar quantity is the one that is conserved in a process.
A scalar quantity is the one that can never take negative values.
A scalar quantity is the one that does not vary from one point to another in space.
A scalar quantity has the same value for observers with different orientation of the axes.
Solution
A scalar quantity has the same value for observers with different orientation of the axes.
Explanation:
The magnitude of a scalar quantity is everything that defines it. As a result, it has the same value for observers with varied axes orientations.
