2008 CSSA:

Effect of earth's orbital and rotational motion on launch of rocket

Explain the impact of Einstein's application of the principle of Relativity on the aether model and this postulate

(Time dilation questions)

Thought experiment

Assess the impact on the environment of the AC generator

(Standard motor/generator questions on Force and Torque)

Debate on waves

Superconductors: advantages, why not used in transport

Force on charged particle in magnetic field

Analyse "The torque of DC motor is a constant 1.5Nm" claim with diagram

Transformers, powerloss calculation, features to prevent power loss

Hertz/Photoelectric effect

Contribution of Einstein/Planck to black body

(generic photoelectric calculations)

Usually the CSSA Catholic Physics trial is a pretty good indication of what will be in the HSC. Did anyone do the test? What kind of questions were asked?

I reckon there will be something on:
- BCS (hasn't been asked since 2005)
- Solar Cells (hasn't been asked in a very long time)
- A thought experiment
- How an induction cooktop/EM breaking/Microphone works
- Something on the slingshot effect

So yeh tell us, Catholic school people, what was in your trial??

solar cells could be dodgy because they changed the DP completly for this year because it was completly wrong.
I think Michelson-Morely, impacts of AC generators, BCS, X-ray cysall. and for Quanta to quarks tipping a question on particle accelators with the LHC this year and all

What did they change about the DP?

The Dot point was changed for last years HSC, to clarify the question asked in the 2004 paper, which didn't really fit under the old DP. They reintroduced the old DP from the 2002 syllabus.
ne thing they haven't asked about is the Space Scientists. Sooner or later it will come up

The solar cells got moved because they don't actually use the photoelectric effect look in the ammendments table on the BOS website, where u get the syllabus

There is debate even among experts in the field, if it should be called the photoelectric effect. I have spoken to some of the leading designers of solar cells at UNSW about this. The agree it isn't the same as the traditional photoelectic effect, in the photoelectron doesn't leave the surface of the metal.

If you go back to the 2002 syllabus, they had solar cells in both sections.
identify data sources gather,
process and present information to summarise the use of the photoelectric effect in:
– breathalysers
– solar cells
– photocells

gather, process and analyse secondary information to describe the relationship in solar cells between the photoelectric effect, semiconductors, electric fields and current

To overcome the debate they changed the wording but they wanted to clear up that you still had to go to the depth of the old second dot point and the brought it back.

What do you think the chances are we'll have to name a scientist and their contributions in the space topic? Have they ever asked that?

BINGO! we have a winner
