The electric field inside a uniformly charged sphere with positive charge Q and radius R points radially outward from the center of the sphere and has magnitude E=Qr/4πϵ0R3 at a distance r from the center. By integrating the electric field, find the potential difference between the center of the sphere and its surface. Which is at higher potential: the center or the surface?

(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.
