The space between two parallel conducting plate each having an area S is filled with an inhomogeneous ohmic medium who e conductivity varies linearly from σ1 at one plate (y=o) to σ2 at the other plate (y=d). A d-c voltage V0 is applied across the plate Determinea) the total resistance between the plates, andb) the surface charge densities on the plate.

Ariver flows from north to south at 8 km/h. a boat is to cross this river from west to east at a speed of 20 km/h (speed of the boat with respect to the earth/ground). at what angle (in degrees) must the boat be pointed upstream such that it will proceed directly across the river (hint: find the speed of the boat with respect to water/river)? a 288 b. 21.8 c. 326 d. 30.2
