(10 points) a cylindrical shell of dielectric of permittivity and inner and outer radii a and b surrounds a very long, conducting cylinder of radius a. the system is placed in an electric field e0, perpendicular to the axis of the cylinder, (a) (8 points) find the potential in the regions r < a, a < r < b, and r > b. (b) (2 points) find the charge per unit area at r = a as a function of the angle measured from the direction of e0.

the temperature and the pressure affect solubility. temperature affects by changing the properties of the solvent. the increase in pressure increases solubility, the decrease in pressure decreases solubility.

your answer is, orbit around the nucleus

when jerome paddle in flowing river towards east the net speed of jerome will increase

so the net speed of jerome will be given as

now the speed of paul will be same as it is given as he is running on the ground

so

so here we can say since the speed of jerome is more so he will win the race

now as we know the distance so the time difference is given as

so jerome will reach first and the time difference will be 203.55 s or 3.4 min
