PLEASE HELP !! ILL GIVE BRAINLIEST A projectile is launched from the top of a 15 m tall building at a speed of 25ms at an angle of 50° above the horizontal. The horizontal distance from the base of the building to where the projectile lands is most nearly

Awave is produced in a rope. the wave has a speed of 33 m/s and a frequency of 22 hz.

The slope of a velocity time graph over any interval of time gives the during that interval

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.
