A spherical dewdrop, when deformed slightly, oscillates about its equilibrium shape. The physically relevant variables to describe the frequency of this oscillation f are its mass M , radius R and a third variable Q , where Q could be either the universal gravitational constant G or the surface tension S . One must decide the relevant variable Q and employ dimensional analysis to express f as f=k M^x R^y Q^z , where
