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 antother in space.

D

A scalar quantity has the same value for observers with different orientations of the axes.

Text Solution

Verified by Experts

The correct Answer is:
D
The statement is false. It is because kinetic energy (scalar quantity) is not conserved during inelastic collision.
(b) The statement is false. It is because the temperature (scalar quantity) can be negative.
(c ) The statement is false. It is because gravitational potential energy (scalar quantitiy) vary from point to point is space.
(d) The statement is true because the value of scalar does not change with orientation of axes.
