- Comment on the difference between a nova and supernova. [Note: There are two basic types of supernova.]Natural gas (CH.) fuel relcases 50 MJ per kilogram of fuel combusted. The reaction is CH, + 20, CO2 + 2H;0 Calculate the energy released per kilogram of CO2 emitted. [Energy released is Eepe E, where Eris energy released per kilogram of fuel combusted, mf is mass of a kilogram-mole of fuel (CH.), and mr is mass of a kilogram-mole of carbon dioxide (CO2). The Molecular mass of an atom of carbon, hydrogen and oxygen are 12, 1 and 16 respectively.]Can you please help with Part 2 of 2? Thank you.
- A supernova’s energy is often compared to the total energy output of the Sun over its lifetime. Using the Sun’s current luminosity, calculate the total solar energy output, assuming a 1010 year main-sequence lifetime. Using Einstein’s formula E=mc2 calculate the equivalent amount of mass, expressed in Earth masses. [Hint: The total energy output of the Sun over its lifetime is given by its current luminosity times the number of seconds in a year times its ten billion-year lifetime; ; mass of earth = 6×1024kg; c = 3×108m/s. Your answer should be 200-300 Earth masses.]What is arrow positioning in comsol multiphysics?
