QCE PhysicsPractice Examination 12

This paper covers

• QCAA Physics Units 3 & 4 (General, 2025 v1.3) External Assessment - Practice EA 12 of 20
• Stimulus thread: HVDC power transmission across regional Queensland - I-squared-R losses, step-up transformers, Faraday's Law
• Unit 3 Gravity & Electromagnetism: circular motion, gravitation, Kepler, orbits, Coulomb's Law, electric fields, motor effect, induction, AC generators, transformers, power transmission
• Unit 4 Revolutions in Modern Physics: special relativity (time dilation, length contraction, mass-energy), quantum theory (Planck, photoelectric effect, de Broglie, Bohr), Standard Model (quarks, leptons, bosons, conservation laws, Feynman diagrams)
• Paper 1 (Section A: 20 MCQ = 20 marks; Section B: short response = 28 marks) + Paper 2 (Section C: data/stimulus extended response = 49 marks); grand total 97
• Assessment Objectives 1-4 only; higher-mark items use evaluate/justify/deduce/compare with full evidence-principle-conclusion reasoning chains
• Every worked solution arithmetically verified in Python; all answers given with correct SI units and significant figures
