Unformatted text preview: pasha (sep635) – HW 82 – Antoniewicz – (56445) 1 This printout should have 16 questions. Multiplechoice questions may continue on the next column or page – find all choices before answering. 001 (part 1 of 7) 5.0 points Of the energy diagrams IVII below, which is appropriate for each of the following situa tions? ≈ 100 MeV (I) ≈ 1 MeV (II) ≈ . 0001 eV (III) (IV) (V) (VI) (VII) Coarse Structure Fine Structure Hadronic (such as Δ + )? 1. V 2. II 3. III 4. VI 5. None is appropriate 6. VII 7. IV 8. I correct Explanation: The energy scale for a subatomic particle (10 8 eV) is much greater than for the atomic level (1 eV). Diagram I is best in this case. 002 (part 2 of 7) 5.0 points Vibrational states of a diatomic molecule such as O 2 ? 1. IV correct 2. V 3. VII 4. III 5. VI 6. II 7. None is appropriate 8. I Explanation: This is similar to the typical energy between two atoms. Diagram IV is the best choice. 003 (part 3 of 7) 4.0 points Idealized quantized springmass oscillator? 1. IV 2. I 3. VI 4. V correct pasha (sep635) – HW 82 – Antoniewicz – (56445) 2 5. VII 6. II 7. III 8. None is appropriate Explanation: A harmonic oscillator has equally spaced energy levels. This is best shown by Diagram V. 004 (part 4 of 7) 4.0 points Nuclear (such as the nucleus of a carbon atom)? 1. VI 2. None is appropriate 3. I 4. IV 5. III 6. V 7. VII 8. II correct Explanation: Nuclear excitations are on the order of about 1 MeV = 10 6 eV. This is best given in Diagram II. 005 (part 5 of 7) 4.0 points Electronic, vibrational, and rotational states of a diatomic molecule such as O 2 ? 1. III 2. I 3. None is appropriate 4. VI 5. II 6. IV 7. V 8. VII correct Explanation: This would be given by the splitting of elec tronic levels due to vibrational and rotational states. Diagram VII is the correct choice. 006 (part 6 of 7) 4.0 points Rotational states of a diatomic molecule such as O 2 ? 1. I 2. III correct 3. VII 4. IV 5. VI 6. V 7. II 8. None is appropriate Explanation: This is the scale of energy for rotational states. Diagram III is correct....
