I'm pretty sure conic sections is either Calc 2 or 3. Calc 3 is basically 1st year uni.

If 4% ionisation and monoprotic, then [H+] = 0.04 X 0.01 = 0.0004 Then pH =-log[H+] = -log[0.0004] = 3.4

The church out the front of my school is a pokestop

Pythagoras once to find 'a' -- it seems you have done this Second Pythagoras comes between 'a' and the vertical displacement of 250m. 'a' vector would lie on the plane which contains the cardinal points (I.e., parallel to earth surface or ) and 'up' is perpendicular to earths surface, so...

Pythagoras twice :)

You need to convert grams into kg :) Just saw your edit :) mm is given in grams/mol rather than kg/mol. So, mass in that eqn is given in grams :)

Hey guys and girls, Places filling pretty quickly. I had 4 spaces taken in the space of 4 hours yesterday. Limited spots remaining.

It would be this exactly! LoL.

It is to do with Le Chat. In an acidified solution, Ba produces ppt with sulfate, but not phosphate due to the relative weakness of the hydrogen phosphate ion. This is because hydrogen sulfate is able to react with water to produce hydronium ions and sulfate ions. Enough sulfate ions are...

As above. How did advances in technology lead to advances in Physics? - invention of telescope -- discovery of other planets, galaxies etc.. Changed understanding of model of the universe -- analysis of spectral shifts led to suggestion of "Big Bang" which was supported by observation of CMBR...

If the teachers at your school aren't the best, I dare say more detailed would be better than a brief overview. I have seen Talents notes and they are VERY brief and sometimes don't even appear to address some dot points. Based on this, I would recommend Matrix. Orrrrrrrrrrr...

Not going at the moment! Been too busy with other projects! Thanks for the continued interest though :) I'm hoping to resume them sometime in the near future :)

Thanks for mentioning me, maths God! I will have an office in Parramatta for HSC 2017, will be offering only Year 12 Physics for HSC 2017. Starting Year 11 Phys and Year 11 Chem in 2017 and first HSC Chem for HSC 2018. If you are interested, please email me :)

IMO - PiF is good to begin with, but I don't think really extends enough on some dot points to give an 'extensive' understanding, sometimes not even a 'thorough' understanding. I personally find In2Physics gives more complete understanding -- goes beyond the syllabus in some key areas...

I may still be running a class from Green Valley if I get the numbers. If you are interested, shoot me an email :)

Alternatively, noting the first 40cm on both sides would provide balancing torques and essentially cancel each other out you would be left with: 1 x 0.3 = 20/100m x 9.8 x 0.5 And you should get the exact same answer.

Actually, just trig :) Post your workings, let's see where you're going wrong

Some trig + circular motion should help you win this.

Yep, this is a massive misconception. Resonance is such a strange term to call this phenomenon, when nothing is actually resonating, lol.

Thanks mate :) You just need to get your hands on past papers tbh, plenty of practice questions in them :)
