Which of the physical quantities does not have the same units:

Explanation

Pressure (denoted by P) and strain are related to the deformation of materials. Pressure is defined as force per unit area (P=F/A), and its units are force divided by area (N/m)2, which is equivalent to Pascal, denoted as Pa). Strain, on the other hand, is the ratio of the change in size to the original size and is dimensionless, meaning it has no units. Therefore, pressure and strain do not have the same units.
