or the force pressing the two surfaces against each other. The constant of proportionality varies depending on the surfaces which are in contact. For example, you might expect smaller friction when two "slick" surfaces – such as a block of ice on a frozen lake – are in contact, and ...

It is basically the classical mass-balance law of continuum mechanics, which expresses that the net mass-flux across the boundaries of a control volume must be equal to the accumulated mass. The first term of Eq. (A.15) accounts for the rate of change of mass at the point, the second ...

For illustrative purposes, consider the one-dimensional case in which the waves are traveling in the x direction. The equation satisfied in this case is (63)c2∂2p∂x2=∂2p∂t2 The most general solution to this equation can be written in the form: (64)p=f1x+ct+f2x−ct This ...
We can further simplify the equation by taking h2 = 0 (we can always choose some height to be zero, just as we often have done for other situations involving the gravitational force, and take all other heights to be relative to this). In that case, we get P2=P1+ρgh1P2=P1+ρgh1...

) for an ion, the driving force acting on the ion would be zero. If Vm = Veq., it can be seen that VDF = Vm − Veq. = 0. In this case, there would be no net movement of the ion across the plasma membrane into or out of the cell (i.e., no net flux of ion). See ...
