Red giants derive their energy from reactions involving helium. In a reaction where 3 helium nuclei change into 1 carbon nucleus. The mass of a helium nucleus is 6.645x10^-27 kg, and the mass of a carbon nucleus is 1.9922x10^-26 kg.

calculate: (1) the mass lost in one such reaction, (2) the energy released in one such reaction, (3) the energy released when a kilogram of helium fuses to become carbon, (4) the ratio between this and the amount of energy released when a kilogram of hydrogen fuses to become helium, and finally (5) the length of time a 10 solar luminosity star of 1 solar mass could continue shining if it were powered by this reaction.

    Problem 5. [Einstein's E = mc²] Sun is producing energy by nuclear fusion reactions converting four hydrogen nuclei to form one nucleus of He, i.e. 4H + He. However, mass of helium nucleus is smaller than that of four hydrogens and this difference is called mass defect. If mass of the hydrogen nucleus is my and mass of the helium nucleus Mhe mass defect of one nuclear reaction Am is equal to Am = 4 *my - Me (1) Using...

    Use the following information to answer this analytic question The sun produces energy through nuclear fusion. In one particular reaction, energy is released when a hydrogen-2 nucleus fuses with a hydrogen-3 nucleus. This produces a helium-5 nucleus that is unstable and that decays to a helium-4 nucleus and a neutron. The fusion reaction chain is H + > - He – În + He The masses of two of these particles are given in the table below. Particle Isotope Notation...

Convection releases neutrinos, which random walk through the radiation zone. Fission in the Sun's core creates neutrinos when protons turn into neutrons. The annihilation of positrons and electrons in the core produces neutrinos. Fusion in the Sun's core creates neutrinos when protons turn into neutrons, QUESTION 11 How does the interstellar medium impact...

    10. Write a one-page summary of the attached paper? INTRODUCTION Many problems can develop in activated sludge operation that adversely affect effluent quality with origins in the engineering, hydraulic and microbiological components of the process. The real "heart" of the activated sludge system is the development and maintenance of a mixed microbial culture (activated sludge) that treats wastewater and which can be managed. One definition of a wastewater treatment plant operator is a "bug farmer", one who controls the aeration...
