Show that in this fusion cycle, the energy released is about 30 MeV.

In summary, the task is to show that in the fusion cycle of the sun, the energy released is approximately 30 MeV. To solve this, one can use the binding energy per nucleon graph and consider the masses of the components in each reaction. It is also important to carefully examine all three reactions, as one of them may seem unusual.

The Attempt at a Solution


Can you do this without any relevant information!?
If you have the binding energy per nucleon graph, can you do it?

Hmmm... I'd consider the possibility that whoever assigned you that problem is expecting you to dig out the relevant data... Indeed, that's probably the point of the problem, because once you have the relevant data there's not much to the problem at all...

Try asking yourself about the masses of the various components in the various reactions.

You might also want to look hard at all three reactions. One of them smells funny.
 

Related to Show that in this fusion cycle, the energy released is about 30 MeV.

1. How is the energy released in a fusion cycle measured?

The energy released in a fusion cycle is typically measured in units of mega-electron volts (MeV).

2. What is the significance of 30 MeV in this fusion cycle?

30 MeV is the approximate amount of energy released in this specific fusion cycle, which is a significant amount of energy.

3. What factors determine the amount of energy released in a fusion cycle?

The amount of energy released in a fusion cycle is determined by the mass difference between the reactants and the resulting product, as well as the binding energy of the nuclei involved.

4. How does the energy released in a fusion cycle compare to that of a fission cycle?

The energy released in a fusion cycle is much greater than that of a fission cycle, as fusion involves combining light nuclei to form heavier nuclei, while fission involves splitting heavier nuclei into lighter ones.

5. What practical applications does the energy released in a fusion cycle have?

The energy released in a fusion cycle has the potential to be used as a clean and virtually limitless source of energy, similar to the process that powers the sun.
