Two ships, a and b, leave port at the same time. ship a travels northwest at 21 knots and ship b travels at 25 knots in a direction 32° west of south. (1 knot = 1 nautical mile per hour; see appendix d.) what are (a) the magnitude (in knots) and (b) direction (measured relative to east) of the velocity of ship a relative to b? (c) after how many hours will the ships be 180 nautical miles apart? (d) what will be the bearing of b (the direction of the position of b) relative to a at that time? (for your angles, takes east to be the positive x-direction, and north of east to be a positive angle. the angles are measured from -180 degrees to 180 degrees. round your angles to the nearest degree.)

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.
