Lamar writes several equations trying to better understand potential energy. what conclusion is best supported by lamar’s work? the elastic potential energy is the same for any distance from a reference point. the gravitational potential energy equals the work needed to lift the object. the gravitational potential energy is the same for any distance from a reference point. the elastic potential energy equals the work needed to stretch the object.

Which statement correctly describes the relationship between frequency and wavelength?

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.
