9.34 *** at a point p on the earth's surface, an enormous perfectly flat and frictionless platform is built. the platform is exactly horizontal — that is, perpendicular to the local free-fall acceleration g p. find the equation of motion for a puck sliding on the platform and show that it has the same form as (9.61) for the foucault pendulum except that the pendulum's length l is replaced by the earth's radius r. what is the frequency of the puck's oscillations and what is that of its foucault precession? [hints: write the puck's position vector, relative to the earth's center 0 as r r , where r is the position of the point p and r = (x, y, 0) is the puck's position relative to p. the contribution to the centrifugal force involving r can be absorbed into g p and the contribution involving r is negligible. the restoring force comes from the variation of g as the puck moves.] to check the validity of your approximations, compare the approximate size of the gravitational restoring force, the coriolis force, and the neglected term m (st x r) x st in the centrifugal force.

In a stagnant pool of water, a crayfish may spend much of its time lying with one side of its carapace near the surface of the water. in this position, it will move the walking legs on that side in a rhythmic back-and-forth motion. explain the likely function of this behavior.
