37. Jupiter at its present location, were a star? What would Earth be like ? Assume this hypothetical Jupiter with 75 × MJ would be a red dwarf with the same density as the Sun but a surface temperature of only 2500 K. What would be its total luminosity, compared to that of the Sun? (Hint: recall that to be a star, Jupiter would have to be 75 times more mass than it has today.)

2) Consider a stellar atmosphere composed of pure helium. You will find the temperature at the middle of the He I partial ionization zone, where half of the He I atoms have been ionized. (Such an atmosphere would be found on a white dwarf of spectral type DB.) The ionization energies of neutral helium and singly ionized helium are Eion-24.6 ev and Eion-54.4 ev, respectively....

Please help me know the right anwser and the process
Consider a metal lattice with atoms separated b 0.143 nm. Electrons will diffract when passing through this crystal if their de Broglie wavelength matches the lattice spacing. What speed (in m/s) of electrons is required for the de Broglie wavelength of the electrons to exactly match the lattice spacing? Answer: Consider the following four famous experiments: 1. Einstein's experiments on the photoelectric effect 2. Young's experiment showing the diffraction of...
