Two boats are anchored in the harbor separated by a horizontal distance of 24m. The boats Bob up-and-down as waves enter the harbor. When one boat is at its highest point the other is also at its highest point and there is one wave crest between them. Each boat makes exactly 6 complete up in down cycles every 36.0 s. The vertical distance between a blue ties in those positions 2.4m.

What is the wavelength, frequency, period, amplitude, and speed?

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.
