A substance's bulk modulus has the same units as this quantity, and is equal to "negative volume times the derivative of ​this value with respect to volume.
A substance's bulk modulus has the same units as this quantity, and is equal to "negative volume times the derivative of ​this value with respect to volume." A reference value of 20 millionths of this quantity's SI unit is used to define the decibel in acoustics. This value is equalized in all directions and at all points in a fluid according to (*) ​Pascal's principle. This value is added to kinetic and potential terms to give a constant in Bernoulli's equation, which implies that this value decreases if a fluid's velocity increases. For 10 points, name this quantity equal to force divided by the area over which it is applied, which is measured in the atmosphere with a barometer.
