G&T 6 Mark Questions
1. Explain the change in resistance of a filament bulb in terms of ions and electrons.
2. A heater is made of metal and has an earth wire connected to it. Explain how the fuse and earth wire together protect the wiring of the circuit.
3. Explain how various structures of a plug were designed with safety in mind.
4. Compare the use fuses and circuit breakers to ensure mains appliances are safe.
5. Compare the use of circuit breakers and residual current circuit breakers (RCCBs) in ensuring main appliances are safe.
6. Discuss how electrical faults in mains appliances can be reduced.
7. Consider what factors should be considered when replacing a bulb. Your answer should consider filament bulbs, low energy compact fluorescent bulbs (CFLs) and low energy light emitting diodes (LEDs).
8. Explain how the solar system formed and why there were elements heavier than iron present when it formed.
9. Outline the stages in the life cycle of a star that is about the same size as the sun.
10. Outline the stages in the life cycle of a star that larger in size than the sun.
11. Outline the main results of Ernst Rutherford’s experiment into the structure of the atom and explain why these results led Rutherford to suggest the existence of the atomic nucleus.
12. Explain the changes that occur in the nucleus and the particles which are emitted during alpha and beta decay.
13. Compare the properties of alpha, beta and gamma radiation.
14. Outline the uses of alpha, beta and gamma radiation.
15. Outline the main features of a nuclear fission reactor.
16. Outline the main features of a nuclear fusion reactor.
17. Describe, in as much detail as you can, how our star (the Sun) formed from the time when there was just dust and gas (mostly hydrogen) up to now when it is in its main stable period.
18. Describe, in as much detail as you can, what forces allow a stable star to exist and how the star may eventually form a black hole.
19. Describe, in as much detail as you can, the life history of a star like our Sun.
