1. Electrical wiring in 3-pin plugs, transformer roles in the National Grid, and high-voltage cable identification. 2. Heating curve interpretation, specific latent heat calculations, and energy transfer in phase changes. 3. Average speed determination, scalar vs. vector quantities, and motion concepts in track-based movement. 4. Resistance variation in electrical circuits, LDR functionality, and graphical representation of resistance changes. 5. Pressure calculation using force and area, hypothesis testing in foot pressure analysis, and data accuracy considerations. 6. Density determination of solids and liquids, volume calculations, and mass-to-volume relationships in materials.
