Diffusion of mass and heat are two important phenomena in fluid mechanics. Please explain these two phenomena and identify how Fick's law of diffusion is different from Fourier's law of heat conduction?
A block rests on a horizontal frictionless surface. A string is attached to the block, and is pulled with a force of 45.0 N at an angle θ above the horizontal. After the block is pulled through a distance of 1.50 m, its speed is 2.60 m/s, and 50.0..
