In proton-proton cycle, four hydrogen atoms combine to release energy

In proton - proton cycle, what is the approximate energy released?

Energy is released from stars due to nuclear fusion taking place in two cycles proton-proton cycle and carbon nitrogen cycle. In these cycles four hydrogen nuclei combine to from helium nucleus. In this fusion reaction in addition to energy how many number of nutrinous are released ?

A proton traps a free electron to form the hydrogen atom of lowest energy level. The wavelength of photon emitted in this process will be (assume initial kinetic energy of the electron to be zero)

An electron and a proton are seperated by a large distance and the electorn approaches the proton with a kinectic energy of 2 eV. If the electron is captured by the proton to form a hydrogen atom in the ground state, what wavelength photon would be given off?

Explain the source of solar energy with the help of proton-proton cycle. What is the role of cadmium rods in a nuclear reactor?

An electron, a proton, α -particle and a hydrogen atom are moving with the same kinetic energy. The associated de-Broglie wavelength will be longest for
