The equation of helium fusion reaction

Answer to Problem 6TP
The fusion reaction of helium is given by the following equation −
Explanation of Solution
Introduction:
The formation of one or more different atomic nuclei and the subatomic particles by the combination of two or more atomic nuclei under the
The following are used to achieve the fusion −
- Thermonuclear fusion
- Inertial confinement fusion
- Beam-beam fusion (Beam -target fusion)
- Inertial electrostatic confinement
- Muon − catalyzed fusion
There are two types of fusion reaction −
- First reaction in which the preservation of the neutrons and protons number is available
- In second type of reaction − conversion between the protons and neutrons The initiation of the star burning available and formation of deuterium by the fusion of two hydrogen nuclei
Where,
Before the reaction − two protons and three neutrons present at left side, same present at right side also
Where,
Positron −
Neutrinos -
Hence, the fusion reaction for helium production is given by −
Conclusion:
In nuclear reaction, the energy is released when the mass of resultant particles is lesser than the initial reactant's mass.

- A spectra is a graph that has amplitude on the Y-axis and frequency on the X-axis. A harmonic spectra simply draws a vertical line at each frequency that a harmonic would be produced. The height of the line indicates the amplitude at which that harmonic would be produced. If the Fo of a sound is 125 Hz, please sketch a spectra (amplitude on the Y axis, frequency on the X axis) of the harmonic series up to the 4th harmonic. Include actual values on Y and X axis.arrow_forwardSketch a sign wave depicting 3 seconds of wave activity for a 5 Hz tone.arrow_forwardSketch a sine wave depicting 3 seconds of wave activity for a 5 Hz tone.arrow_forward
