WebNow a function which has a derivative proportional to itself is an exponential, and the solution of this differential equation is n = n0e − mgh / kT. Here the constant of integration, n0, is obviously the density at h = 0 (which can be chosen anywhere), and the density goes down exponentially with height. Fig. 40–2. WebIn the philosophy of thermal and statistical physics, the Brownian ratchetor Feynman–Smoluchowski ratchetis an apparent perpetual motionmachine of the second kind(converting thermal energy into mechanical work), first analysed in 1912 as a thought experimentby Polish physicist Marian Smoluchowski.[1]
Good, but perhaps a bit too easy and a bit unfocused.
WebMar 1, 2024 · Feynman argued that in the equilibrium state, the kinetic energy due to the purely horizontal motion of the piston is 1/2m1v1^2, where m1 is the mass of the piston and v1 is its horizontal velocity. He assumed that the piston has a negligible vertical motion, so the total kinetic energy of the piston is also 1/2m1v1^2.
