Hey all I'd like to help me..
thnx in advance
here z tha Q's :
1) Two plane parallel conducting plates each have area S and are separated by a distance b.
One carries a charge +Q ; the other carries a charge -Q. Neglect edge effects
a) What is the charge per unit area on each plate ? where does it reside ?
b) what is the electric field between the plates ?
c) what is tha capacitance ?
d) As the plate separation is increased, what happens to E, v and C ?
e) If a dielectric is inserted b/w the plates, what happenes to E, v and C ?
.....
2) The distance L that oxygen can diffuse in the steady state is approximately L= √(CD/Q)
, where C is the oxygen concentration, D is the diffusion constant, and Q is the rate per unit volume that oxygen is used for metabolism
a) show that L has dimensions of length
b) The diffusion of oxygen in air is about 10,000 times larger than the diffusion of oxygen in water . By how much will the diffusion distance L change if oxygen diffuses through air instead of water, all other things being equal ?
thnx in advance
