The air force thunderbirds aerial demonstration team is performing at an air show located on earth's magnetic equator. how should any one of the airplanes fly in order to produce the maximum charge separation between its wing tips? (consider both the direction of motion and the orientation of the wings.) the airplane could fly toward the not with its wings pointing east and west. the airplane could fly straight up with its wings pointing north and south. the airplane could fly toward the south with its wings pointing up and down. the airplane could fly straight down with its wings pointing east and west.

Carbon is allowed to diffuse through a steel plate 15 mm thick. the concentrations of carbon at the two faces are 0.65 and 0.30 kg c/m^3 fe, which are maintained constant. if the preexponential and activation energy are 6.2 x 10-7 m2 /s and 80,000 j/mol, respectively, compute the temperature at which the diffusion flux is 1.43 x 10^-9 kg/m^2 -s.
