NCEA Level 3 Excellence Synthesis Prompt:

"A deep-space probe travelling at $0.8 c$ relative to Earth ( $γ = 1.67$ ) is powered by a Deuterium-Tritium fusion reactor ( $Δ E = 17.6 MeV$ ). Its optical sensor uses potassium ( $Φ = 2.30 eV$ ) illuminated by $350 nm$ UV light. How do you structure a multi-part solution?"

Unpack: Break it into 3 clear physics modules: 1. Relativity ( $t = γ t_{0}$ ), 2. Nuclear ( $Δ E = Δ m c^{2}$ ), 3. Quantum ( $E_{k, m a x} = h f - Φ$ ). Clear unit conversions ( $eV \times 1.6 \times 10^{- 19} J$ ) are essential!

Level 3 Physics 10-Section Mastery Checklist (15 min)

1. Quantum Physics Modules (Sec 1–3)

Photoelectric Effect ( $E_{k} = h f - Φ$ ), De Broglie Wavelength ( $λ = \frac{h}{p}$ ), Bohr Atom & Rydberg Formula ( $\frac{1}{λ} = R_{H} (\frac{1}{S^{2}} - \frac{1}{L^{2}})$ ).

2. Nuclear & Relativity Modules (Sec 4–9)

Mass Defect ( $E = Δ m c^{2}$ ), Decay Kinetics ( $N = N_{0} (0.5)^{n}$ ), Fission/Fusion, Special Relativity ( $t = γ t_{0}, L = L_{0} / γ$ ), Relativistic Energy ( $E = γ m_{0} c^{2}$ ), and PET/Solar Tech.
