According to Quantum Mechanics, the ball can be considered to be at the top of its path as well as everywhere else at the same time. There is only a higher probability of finding the ball at the top of its path at any given moment. You need to calculate the Wave Function of the Ball to work out...

It seems like a perfectly good question. There are eight elements in the third period. They each have very different electronegativities, some are electron donors (Na, Mg, Al) and some are electron acceptors (P, S, Cl). Si is an interesting case to discuss. Then there is Ar which doesn't form...

Here is a website that I like: Java Chemistry Lab It's coded in JSmol and it lets you drag and drop atoms to make covalently bonded molecules and ionically bonded lattice. Another good one is run by Dr Karl Harrison, and it also uses the JSMol library: https://3dchem.com

If you have some time, go watch this video by Drs Hume and Ivey, It's all about relative velocity. Pretty cheesy, but absolutely 100% relevant to solving your problem. Frames of Reference (1960)

Too hard to call. Ask one of the students in Year 12 what they did last year, and it's bound to be something similar.

Oooh yeah, how about a depth study on Hunga Tonga-Hunga Ha'apai (Tonga) eruption, January 2022? (for Module 6)

Hydroxide ions don't react with un-dissociated propionic acid molecules (that's the molecule on the left). Hydroxide ions react with the hydrogen ions on the right. If you decrease the concentration of hydrogen ions it favours the forward reaction. Do you get it now?

This discussion lies totally outside high school syllabus. There are two ways that Iron(II) hydroxide can dissolve. Iron(II) hydroxide has a region of solid stability between pH 8 and pH12. The stability of the various hydroxides of iron can be conveniently shown on the Pourbaix Diagram. I have...

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?
