- Estimate the temperature that the surface of the sun would have to be in order to find equal populations of neutral hydrogen atoms and protons at the surface.arrow_forwardIn the Sun's core, thermonuclear reactions produce the energy which 2. eventually produces the Sun's luminosity. The Sun's core has a temperature, Tcore 1.6 x 107 K. The mass density of the core is approximately p= 1.5 x 10 kg m3. Assuming the core has the same mass fraction of hydrogen as the Sun's atmosphere (XH = 0.75), approximate the number of fusion reactions between two hydrogen nuclei (two free protons) per second. You may assume that the temperature and density are uniform throughout the core (not realistic!), which extends from the center of the sun out to about Ro/5, and that particles within the core act like a non-relativistic ideal gas (Maxwellian velocity distribution) with all reactions happening at the same relative velocity. Also assume the cross-sectional area for a proton-proton reaction is o = 2.75 x 1048 m2. %3Darrow_forwardFor a star with the same radius as the Sun, but with a mass twice that of the Sun; a) What is the average pressure lower limit value? b) What is the lower limit value for the average temperature according to the minimum and maximum limit values of the average molecular weight?arrow_forward

Assume that the two palladium nuclei adopt a spherical shape immediately after fission; at this instant, the configuration is as shown in the figure attached. The size of the nuclei in the figure can be calculated from the size of the uranium nucleus because the nucleus material maintains a constant density (the initial nuclear volume equals the final nuclear volume). a) Calculate the electric energy of the uranium nucleus before fission. b) Calculate the total electric energy of the palladium nuclei in the configuration shown in the figure, immediately after fission.
