An insulating sphere of radius a, centered at the origin, has a uniform volume charge densityrho.
A spherical cavity is excised from the inside of the sphere. The cavity has radius \frac{a}{4} and is centered at position h_vec, where |\vec{h}|<\frac34 a , so that the entire cavity is contained within thelarger sphere. Find the electric field inside the cavity.
Express your answer as a vector interms of any or all of rho, epsilon_0, r_vec, and h_vec.

(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.
