(III) Two positive charges are affixed rigidly to the x axis, one at and the other at A third charge of mass m, which is constrained to move only along the x axis, is displaced from the origin by a small distance and then released from rest. (a) Show that (to a good approxima- tion) will execute simple harmonic motion and deter- mine an expression for its oscillation period T. (b) If these three charges are each singly ionized sodium atoms at the equilibrium spacing typical of the atomic spacing in a solid, find T in picoseconds.

(science)study the following ocean currents map. an ocean currents map is shown. on the map the locations for san diego, california and savannah, georgia are marked. there is a looping current from the north past san diego and a looping current from the south near savannah which statement is most likely correct about the average temperatures in san diego, california as compared to savannah, georgia? it is higher in savannah because of the cool ocean currents from the south. it is higher in savannah because of the warm ocean currents from the north. it is lower in san diego because of the warm ocean currents from the south. it is lower in san diego because of the cool ocean currents from the north.
