An automobile has a vertical radio antenna 1.45 m long. the automobile travels at 70.0 km/h on a horizontal road where earth's magnetic field is 50.0 µt, directed toward the north and downward at an angle of 65.0° below the horizontal. (a) specify the direction the automobile should move so as to generate the maximum motional emf in the antenna, with the top of the antenna positive relative to the bottom. north east west south (b) calculate the magnitude of this induced emf. mv

Asheet of steel 1.5 mm thick has nitrogen atmospheres on both sides at 1200oc and is permitted to achieve a steady-state diffusion condition. the diffusion coefficient for nitrogen in steel at this temperature is 6 x 10- 11 m2 /s, and the diffusion flux is found to be 1.2 x 10-7 kg/m2 -s. also, it is known that the concentration of nitrogen in the steel at the high-pressure surface is 4 kg/m3 . how far into the sheet from this high-pressure side will the concentration be 2.0 kg/m3 ? assume a linear concentration profile.
