Using the radial eqtn. of motion, we can derive an equation for small oscillations of the system when the orbit deviates a little bit from circular (actually we can do it for small oscillations around any closed orbit, but this is a little harder). we do this here for 2 different potentials consider a central field with a newtonian potential, such that v(r) ="v_0/r. find first of all, when the system has a given angular momentum l, what is the value r_0 of the radius for which the orbit is circular; and determine also the orbital period of this orbit (ie., for the angular motion). then make a taylor expansion of the radial potential up to 2nd order in the deviations of r from r_0 and use this to find the frequency of harmonic oscillations of r around r_0. how does this frequency compare with the frequency of orbital motion when r = r_0? now do exactly the same for the 2 - d harmonic potential, where v(r) = kr62/2\ ie., first find r_0 for circular orbits, then find the period of revolution around the z axis, and finally find the frequency of small oscillations around r-0

Researchers determine that the biodiversity in a woodland region is declining. they identify two major threats to the region's biodiversity, a method to address each threat, and the expected outcome of each method. this information is shown in the table. a) reforestation would not benefit many species because most forest species live on the ground. b) reforestation would take the longest time to be effective because trees take several years to grow. c) biological augmentation would benefit only a few species because is is typically not very effective. d) biological augmentation would take less time to ve effective because it targets the majority of prey species.
