Which of the following is NOT a product of the first step in the p-p chain of nuclear fusion?
a form of hydrogen
a positron
a neutrino
a deuteron
a form of helium
Answer- a deuteron
1H+1H----> 2H+e++v
2H+1H------>3He+ gamma ray
where e+- positron and v- neutrino.

HW 5/7: Find the amount of energy released in each step of the Proton-Proton chain Fusion in the Sun follows a process called the Proton-Proton chain, starting with 6 total hydrogen nuclei 1. Two hydrogen nuclei fuse to form a deuterium (2H) nucleus, expelling a positron and a neutrino. (x2) 2. The deuterium nucleus fuses with a hydrogen nucleus to form a helion (He), expelling a gamma ray. (x2) 3. Two of these helion nuclei fuse to form a Helium...
A) You will investigate the PP-I chain leading to the formation of helium and energy from the fusion of 1) Demonstrate that I u of mass (1/12)mC, atom) has an equivalent rest mass of answers Qi, Q2, and Qs in MeV. Be careful with Qi-beware of the leptons! hydrogen in the cores of lower mass main sequence stars such as our Sun. 931.4940954 MeV/c (match at least the first 4 digits past decimal) Calculate the Q value for each step...

Question: Write at least two paragraphs discussing things that you learned from the background portion of this lab. Be sure to include your interpretation of why nuclear fusion does not occur naturally on the Earth as well as why we do not yet have the technology to replicate the process. lab/Background Information: Nuclear fusion is a very important physical process that governs how the Universe evolves. It occurs naturally in stars, but has not been observed to occur naturally anywhere...
Nuclear fusion in the stars occurs by a series of reactions. Identify X, Y, and Z in the following nuclear reactions that ultimately convert hydrogen into helium. Give all nuclei in the form X. 12 b. H + H - Y
The proton-proton (p-p) chain reaction is presently the source of (nuclear) energy in the core of stars. This reaction releases 6.0 times 10^-14 J/kg. Consider a star with a total mass of 4.15 times 10^30 kg; the p-p chain will convert 10% of its mass (core mass) to helium. If the total power (luminosity) of the star is 8.2 times 10^20 W, how many years can it produce energy by this reaction?
Q: Which of the following are manifestations of solar magnetic activity? sunspots flares prominences all of the above Q: How did the system of planets orbiting the Sun form? he planets formed from the same materials as the Sun, assembled to current organization by gravity and angular momentum. The planets and the Sun formed at the time of the Big Bang. The planets were captured by the Sun’s gravity. The planets formed from the fusion of hydrogen in their cores....
Please give clear and correct solutions. Need help. University
astronomy. Thanks
Briefing As we have seen, the Sun's energy comes from a series of nuclear fusion reactions (the p-p chain) in which 4 protons (Hydrogen nuclei) fuse to produce a "He nucleus. The original 4 protons have a higher net mass than the "He nucleus and the missing mass is converted to energy mostly in the form of gamma rays. Eventually, this energy (now degraded to visible light photons) is...
