Two wooden boxes of equal mass but different density are held beneath the surface of a large container of water. box a has a smaller average density than box b. when the boxes are released, they accelerate upward to the surface. which box has the greater acceleration?

(a) it depends on the cotent of the boxes
(b) box b
(c) they are the same
(d) we need to know the actual densities of the boxes in order to answer the question
(e) box a

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.
