the number density of free electrons in a copper conductor is 8.5×10^28m^-3.how long does an electron take to drift from one end of a wire 3.0m long to it's other end? the area of cross section of the wire is 2.0×10^-6m^2 and it is carrying a current of 3.0A

(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.
