Question

About 2% of the energy generated in the Sun’s core by the p-p reaction is carried out of the Sun by neutrinos. Is the energy associated with this neutrino flux equal to, greater than, or less than the energy radiated from the Sun’s surface as electromagnetic radiation?

Short answer

The energy flux of the neutrino flux is less than the energy radiated by the sun as electromagnetic radiation.

Step-by-step solution

p-p Reaction

The energy generated on the sun is due to the nuclear fusion of the two hydrogen atoms. Each proton of both hydrogen atoms forms an atom of Deuteron with a neutrino and a positron. The positron is neutralized by an electron which produces gamma-ray photons. The deuteron production occurs once by the interaction of 10²⁶ proton-proton interaction.

Whether the energy of neutrino flux is equal, greater, or less than energy radiated by the sun as electromagnetic 

The energy flux of the neutrino flux is less than the energy radiated by the sun as electromagnetic radiation because neutrino produces for every 10²⁶ proton-proton interaction.

Therefore, the energy flux of the neutrino flux is less than the energy radiated by the sun as electromagnetic radiation.
