Ok, this is ignoring the multiple choice questions, there's no use trying to predict them anyway.
Obviously the exam paper will have content that was also in the previous 4 exams; there's pretty much always going to be projectile motion question, a question on a motor, a question on transformers... etc.
But if the exam writers want to use the parts of the syllabus that did not prominently feature in the last 4 exams, you could expect questions on:
SPACE:
- Present info on the rocket scientists
- Comparing low earth and geostationary orbits
- Orbital decay
- Safe re-entry into atmosphere and landing, incl. angle of re-entry.
- Newton's Law of Universal Gravitation, and the Slingshot Effect.
- Implications of Relativity on Space Travel (although relativity of its own right has been very thoroughly examined, especially the MM experiment)
- Einstein's Thought Experiments, relationship between thought and reality, and relationship between theory and evidence. (maybe)
MOTORS & GENERATORS
- Torque; Fd or BiancosX (neither have been touched on; force between parallel current carrying wires has come up a lot, however)
- Application of motor effect to Galvanometer and Loudspeaker
- Faraday's Law, concept of magnetic flux density (maybe)
- Application of eddy currents to electromagnetic breaking (Lenz' law in general has been thoroughly examined, and also they've asked about cooktops once)
- Comparison between generators and motors; AC and DC (maybe)
- First hand investigation to demonstrate production of AC
- Investigation to model transformers and how secondary voltage is produced (hasn't been touched yet)
- vp/vs = np/ns problems
- Discuss how eddy currents in transformers are overcome
- Impact of transformers on society (has only been asked indirectly - has not had a full 8 marker dedicated to it with direct syllabus quotation in the question)
- Analyse energy transfers/transformations; conversion of electrical energy into useful forms in home and industry (maybe...)
IDEAS TO IMPLEMENTATIONS
- Cathode Ray Tube Experiments (cathode rays in general have barely been touched, the exam writers favoured p-e effect, semiconductors and superconductors)
- The role of components in a TV (electrodes, plates/coils, fluoro screen)
- How forces (E or B) are used to manipulate stream of charbed particles (maybe)
- Hertz' Experiment (there is 3 dotpoints on this and it hasn't been touched) and also the 1st hand investigation to produce/receive radio waves
- Planck's Hypothesis - Quantisation (there has been a question directly on Einstein's contribution, but not Planck's hypothesis)
- The Einstein/Planck's differing views mini-essay has not come up yet...
- Discussing how shortcomings in old technology lead to the development of transistor thru increased knowledge of properties (maybe)
- Electrons in solids being shared between atoms, moving freely (maybe)
- Use of germanium because we didn't know how to extract better stuff (maybe)
- Doping, differences between p and n type semiconductors (all these maybe's are because semiconductors themselves have been frequently asked about, but it's just these 3 or 4 dotpoints have not been DIRECTLY asked about, although aspects of them would have been mentioned in answering the other questions, since several of them were of a high mark value)
- Impact of transistors on society... (rama_v was correct... They've done impact of generators, transformers, superconductors on society, but not transistors yet)
- Describe conduction as free movement of electrons
- Identify that resistance is scattering of electrons by lattice
- Discuss BCS theory (has indirectly come up already)
- Process info to identify the metals, alloys, compounts used as superconductors (superconductors have also been frequently asked about, but once again there's a few dotpoints that weren't DIRECTLY examined)
- Use of superconductors in transport and power generation/distribution has only come up once, I think it was a 2, 3 or 4 mark question. Because there's 3 dotpoints on it, I'd say there's some chance it'll come up again.
