1. Electric Circuits and Resistance Calculation – Determination of resistance in a nichrome wire using given resistivity and dimensions. 2. Electromagnetic Induction and Faraday’s Law – Explanation of why current in a simple electric motor rises to a maximum and then decreases, referencing Faraday’s and Lenz’s laws. 3. Rotational Motion and Centripetal Acceleration – Derivation of the equation for centripetal acceleration based on velocity vector diagrams. 4. Particle Physics and Standard Model – Description of the standard model, including fundamental particles and their interactions. 5. Higgs Boson and High-Energy Collisions – Calculation of the Higgs particle’s mass in GeV/c² and explanation of why high-energy collisions are required in particle accelerators. 6. Electric Fields and Ionisation – Analysis of whether air molecules ionise at a given distance from a charged sphere based on electric field strength.
