What is the dewpoint temperature when the dry-bulb temperature is 12 and the wet-bulb temperature is 7 c

We put a force of 50n on an object and the acceleration is 100 m/s². what is the mass of the object?

What is a possible result of higher air temperature caused by global warming

Carbon is allowed to diffuse through a steel plate 15 mm thick. the concentrations of carbon at the two faces are 0.65 and 0.30 kg c/m^3 fe, which are maintained constant. if the preexponential and activation energy are 6.2 x 10-7 m2 /s and 80,000 j/mol, respectively, compute the temperature at which the diffusion flux is 1.43 x 10^-9 kg/m^2 -s.
