Aparticle of mass m and charge +q is confined to move in a horizontal rod situated a distance d above two charges of +q that are fixed a distance 2d apart. the line connecting the two +q charges is parallel to the rod. the charge +q is fixed to move between and above the two charges. what is u(x) for this particle where x is the distance along the rod from a point equidistant and above the +q charges? find the frequency of small oscillations from the equilibrium

(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.
