Sabendo que a energia cinética pode ser determinada usando a equação EC = (½)m. v2, calcule a energia cinética associada à um carro, com massa de 1500 kg, que se move com velocidade de 20 m/s.

What is relative velocity? in which condition is relative velocity known by adding the velocity of the first body and that of the second body

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.
