The only elastic modulus that applies to fluids is
Correct answer: D. Bulk modulus
- A. Young's modulus
- B. Shear modulus
- C. Modulus of rigidity
- D. Bulk modulus
Explanation
The correct answer is the Bulk modulus. This modulus is crucial for understanding how fluids respond to changes in pressure, which involves volume changes. Unlike solids, fluids cannot sustain shear stress, so moduli such as Young's modulus, shear modulus, and modulus of rigidity, which relate to shape change under stress, do not apply to fluids.
