The correct answer is: D. is independent of pressure and viscosity.
The bulk modulus of elasticity is a measure of how difficult it is to compress a material. It is defined as the ratio of the change in pressure to the corresponding fractional change in volume. The bulk modulus has units of pressure, such as
pascals (Pa).The bulk modulus of a material is independent of pressure and viscosity. This means that the bulk modulus of a material will not change if the pressure or viscosity of the material changes.
Option A is incorrect because the bulk modulus has units of pressure, not 1/pressure.
Option B is incorrect because the bulk modulus is independent of pressure.
Option C is incorrect because the bulk modulus is not necessarily large when a fluid is more compressible. The bulk modulus of a fluid depends on the type of fluid and its temperature.
I hope this helps! Let me know if you have any other questions.
