A physical pendulum consists of an 85-cm-long, 240-g-mass, uniform wooden rod hung from a nail near one end (Fig. 14-38). The motion is damped because of friction in the pivot; the damping force is approximately t proportional to d6/dt. The rod is set in oscillation by displacing it 15 from its equil

Aquaporins exclude passage of hydronium ions (H30+). But recent research has revealed a role for some aquaporins in fat metabolism, in which they allow passage of glycerol, a three-carbon alcohol (see Figure 5.11), as well as H20. Since H30+ is much closer in size to water than is glycerol, what do y
