Answer:
The correct answer is d) a scalar quantity has the same value for observers with different orientations of the axes
(a) Scalars can have both positive and negative values, for example, Temperatures as low as -20 degrees Celsius have been recorded. As a result, the preceding statement is incorrect.
(b) While scalar values have dimensions, they do not have any directions associated with them. Distance is both a scalar and a three-dimensional quantity. As a result, the assertion is incorrect.
The gravitational potential, for example, is a scalar quantity that can vary from one place in space to another.
(d) Because a scalar quantity does not change with respect to the axes, the statement above is correct.
