A football (American football) receives the ball and runs north. He then has to run back south, dodge the opposing team's defense east and west, then runs back north for a touchdown. Measuring from where he first received the ball, what is bigger, the magnitude of his displacement, or the magnitude of the distance he traveled? Or were they the same? A - The magnitude of the distance was greater than the magnitude of the displacement.

B - The magnitude of the distance was less than the magnitude of the displacement.

C- The magnitude of the distance was the same as the magnitude of the displacement.

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.

Arigid tank is divided into two equal parts by a partition. one part of the tank contains 3 kg of compressed liquid water at 400 kpa and 60°c while the other part is evacuated. the partition is now removed, and the water expands to fill the entire tank. determine the entropy change of water during this process, if the final pressure in the tank is 40 kpa. use steam tables.
