When a fluid is incompressible, it means:
Correct answer: D. Its density remains constant
- A. No internal frictional force
- B. Independent of coordinates
- C. Independent of time
- D. Its density remains constant
- E. Its density remains variable
Explanation
When a fluid is incompressible, it means, its volume or density does not change with changes in pressure.

About Physics of Solids
Solids are compared through crystal structure, amorphous arrangement, elasticity, plastic deformation, stress, strain and Young’s modulus. Electrical behavior depends on available charge carriers and band structure, so conductors, insulators and semiconductors must be distinguished from mechanical properties such as strength, stiffness and brittleness.
