Para cada rapidez en la figura 2.9, ¿cuáles son (a) la distancia recorrida entre t = 0 y t = 1.50s y (b) la relación entre la distancia recorrida y el intervalo de tiempo correspondiente? Para cada rapidez, ¿cuáles son (c) el intervalo de tiempo requerido para pasar de x = 2.00 m a x = 3.50 m y (d) el cociente entre la distancia recorrida y el intervalo de tiempo correspondiente?

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.

How to tell if two objects are in thermal equilibrium 1.the objects have the same temperature 2.the objects are the same size 3.the objects are touching each other 4.the objects temperatures are changing

Aphoton is absorbed by an electron that is in the n = 3 state of a hydrogen atom, causing the hydrogen atom to become ionized. very far away from the nucleus, the released electron has a velocity of 750,000 m/s. what was the wavelength of the absorbed photon?
