Statement: Calculate the binding energy per nucleon for ( ^5626\textFe ). Given:
( m_p = 1.007276 ,\textu,; m_n = 1.008665 ,\textu,; m\textFe-56 = 55.934938 ,\textu,; 1,\textu = 931.5 ,\textMeV/c^2 ).
Solution:
Number of protons ( Z=26 ), neutrons ( N=56-26=30 ). El término "Acosta320" aparece en foros de estudiantes
Mass defect:
[
\Delta m = [Z m_p + N m_n] - m_\textFe
= [26(1.007276) + 30(1.008665)] - 55.934938
]
Compute: ( 26\times1.007276 = 26.189176 ) u; ( 30\times1.008665 = 30.25995 ) u; sum = 56.449126 u.
Subtract Fe mass: ( 56.449126 - 55.934938 = 0.514188 ) u. Conclusión: "Acosta320" no es una obra legítima
Binding energy: ( B = 0.514188 \times 931.5 ,\textMeV \approx 479.0 ,\textMeV ).
Per nucleon: ( B/A = 479.0 / 56 \approx 8.55 ,\textMeV ).
| Option | How to Access | Typical Cost / Requirements | |--------|----------------|------------------------------| | University Library | Most physics‑oriented libraries keep a copy of the solucionario for reference. | Free with student/faculty credentials. | | Official Publisher Website | Search for “Virgilio Acosta Solucionario Física Moderna 320”. Often the publisher sells a print copy or a PDF download. | Print: ~ $30‑$45 USD; PDF: ~ $20‑$35 USD (depending on region). | | Course Reserve | In some institutions the instructor places the solution manual on reserve (short‑term loan). | Free, limited borrowing period. | | Authorized E‑book Platforms | Platforms like SpringerLink, Elsevier’s ScienceDirect, or regional e‑book services (e.g., e‑Libro, Google Play Books) may host a licensed electronic edition. | Subscription or per‑chapter purchase. | | Second‑hand Bookstores | Physical or online second‑hand shops (e.g., Librería Gandhi, MercadoLibre, Amazon Marketplace) often list used copies at reduced price. | Usually 30‑60 % of the new price. | | Inter‑library Loan (ILL) | If your home library does not own the title, request it through ILL. | No cost (or a minimal shipping fee). |
