Aparallel-plate capacitor initially has air (k= 1) between the plates. we first fullycharge it by a 12 v battery. after the battery is disconnected, we insert a dielectricbetween the plates and it completely fills the space in between. a voltmeter is placedacross the capacitor and it reads 3.6 v now.(a) assuming that there is no charge loss during the process, what is the dielectricconstant of this material? (b) what’s the fraction of the stored energy changed by inserting the dielectric? (c) what will the voltmeter read if the dielectric is pulled partway out so that it fillsonly half of the space in between the plates?

(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.
