I think you mean "ionising power" . Alpha particles carry 2 units of positive charge. They travel in dead straight lines about 3 cm in air before they are all stopped by collisions with air molecules. Alpha particles have lots of momentum. Beta particles are very light, they carry one unit of...

The short answer is: practically Zero solubility. Iron(II) hydroxide is almost insoluble in water, it's solubility constant is 4.1 x 10-15. It only starts to become sparingly soluble once the pH starts to get up around 12. Here is how you do these calculations. You can't just halve the...

STRIVE Physics 12 by Odlum & Garner is still available. Go to https://www.odlumgarner.com.au or you can order through any educational bookseller.

If all you want is "grind" then go get a copy of Dot Point Physics by Shadwick (Science Press 2018). 350 pages of "grind". That should sate your appetite.

Storyboard everything. Tell your story consistently. Have a worked out creative plan for everything on the timeline. Ensure everything relates to the theme. If you are filming any content, spend a lot of time researching your locations. If you are looking for inspiration, I reckon any music...

Critical theories are a response to dissatisfaction with the current structures. Critical theories arise within the dominant culture and political structure. Therefore critical theories seek to reform or over-turn the current structures. Colonialism is not a theory because it arose through the...

Yes. First you need to distinguish natural disaster from man-made political disaster. A major volcanic eruption is a natural disaster. A war is a political disaster. Deforestation is a man-made ecological disaster. There is plenty written about human-induced climate change. Go look up the United...

RE: rawmarks.info If you are seeing large normalisation adjustments being applied to Business Studies examination and small normalisation adjustments being applied to Physics examination, all that is saying is Business Studies examination from year-to-year is quite inconsistent, and Physics...

Everyone's talking about the efficiency of storing the information, but nobody is talking about the efficiency of retrieving and displaying the information. Think about the extra coding if this field is stored as Boolean type (0 or 1). Then you have to use extra CPU time to convert what...

If you want to know exactly how NESA defines these terms validity, reliability and precision in scientific investigations, I recommend you download this document from the NESA website: Evaluating Scientific Data Stage 4 - Stage 6

What is Engineering Studies? The NSW Engineering Studies syllabus caters for students of all abilities who like building, designing, prototyping and generally figuring out how manufactured products and the built environment really work, from first principles. It combines four focus areas: Scope...

Did you go on the excursion to ANSTO? I don't have all the answers to the excursion booklet, but the questions aren't that hard, that's if you were listening during the excursion. Which questions are you having trouble with?

You need to consider all the possibilities. Look at the figure below. In this example I have a pH indicator that transitions maybe 1 pH unit on the low side of the true equivalence point. As you can see, the error that is introduced will depend on which direction you are titrating from. The...

You're right. There is a difference in the way marking criteria are applied in these two subjects. I think there is a cultural difference, as in scientific cultural difference. Analytical Chemists value accuracy, validity and not over-stating the precision in a measurement or a calculation. When...

Have you downloaded the past HSC Exam Packs? https://educationstandards.nsw.edu.au/wps/portal/nesa/resource-finder/hsc-exam-papers This is the best free resource. You should also pick up a copy of the VET Electrotechnology Curriculum Framework Stage 6 Syllabus from the NESA website.

I reckon there is one standout YouTube channel you should bookmark. It is Bozeman Science, run by Paul Anderson. There is really only one book series that has what you need if you want to work ahead independently. Pearson Year 11 Skills And Assessment (Chemistry) and Pearson Year 11 Skills And...

I have used them all, and honestly the best series is the Pearson Chemistry series (student book and skills and assessment book), and Pearson Physics (student book and skills and assessment book). The editorial teams behind each series are extensive and very well qualified, the attention to...

I would have written it this way, it seems a bit clearer to me, and yes the constant for the definite integral should not appear at this stage: y=\int\int(3x^2-2x+1)\,dx\, dx

Here is an extract from the Stage 6 Design and Technology syllabus: I feel that you would enjoy the D & T course more than IPT. There are parts of IPT that are relevant to your interests, but there is also a lot of stuff in IPT (Transactional Processing Systems etc) that you might not enjoy so...

Here is a direct quote from the NSW Engineering Studies Stage 6 Syllabus. As you can see, Year 11 reports are expected to be less rigorous, but Year 12 reports are expected to "reflect actual engineering practice".
