[amp_mcq option1=”has the dimensions of 1/pressure” option2=”increases with pressure” option3=”is large when fluid is more compressible” option4=”is independent of pressure and viscosity” correct=”option4″]
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.
