Ok, we all know that V=IR SO by that R=V/I So, as Current increases shouldnt resistance in a wire decrease? But power loss increases with an increase in current (P=I^2R) So Im confused Edit: In power transmission actually

So... Had mine Wednesday Ridiculously Hard They went off testing dotpoints and starting testing abstract Ideas from it Like explaining the Zeeman effect Or categories of superconductors Anyone else do this test?

I think I will just go with the Shut up and Accept it method philosphy Until I learn otherwise in anycase

What I would have liked my teacher to do: Explain the concepts, then show how it is asked in exams, and the correct way to answer it Pracs whenever possible (though physics isnt big on pracs) Random Demonstrations are always fun

Remember, With chemistry you are working with whats happening inside the cell.. That is anode -ve cathode +ve Whilst physics deals with what happens outside the cell , Thus electrons come from the cathode and flow to the anode (Conventional current) Anyone know why we havent changed...

Wow, Our teacher believes in self directed learning, so he came up with these guides for each elective So everyone gets to choose The downside: We learn from Excel HSC physics text book, as well as a myriad of text books older then I am Which gets tedious Oh but our teacher is always...

The best things Ive found with Ideas to implementation is just to shut up and accept that we are learning from a text book And that the HSC is basically a test where no matter how correct we are, they have a little marking guideline saying what should be right. So, Coopers pairs, Positive...

I did it in year 11! The test was crazy hard Seriously I looked at the questions, and laughed Yet somehow I got a distinction! Woot for resume materials!

Its times and working out like this, which make you question: Is it worth it for those 2 or 3 marks?

Well Chem isnt too bad, just memory work mixed with the concepts Phys is conceptual, which can be bad Overall, if you look at the 2 hsc exams The physics one is much harder Or atleast I would say

Ahah it is But its a minor dotpoint stating: Identify the industrial source of ethylene from the cracking of some of the fractions from the refining of petroleum And regarding the coordinate covalent bond question There was a multiple choice question on it in the HSC: it was a number 12 (no...

Re: CSSA Bio exam thoughts And the other 7% is found dissolved in the plasma Um, is the Independant Bio trial normally easier or harder then the CSSA? I just did mine (independant), it was pretty basic

Thank you! You just saved me for my trials I want your babies

Question 1 reminds me of a chemistry past paper hsc multiple choice question Water can to form a Hydronium Ion HF can and Ammonia can to form Ammonium No idea what they want with part 2

Re: Maintaining a Balance Products of metabolism are: CO2 and Nitrogenous Wastes CO2 combines with the blood forming hydrocarbonate ions, which dissasociate to make the blood more acidic = bad for homeostasis Nitrogenous wastes are extremely poisonous and so need to be diluted/converted as...

Ouch, tough question Chemical composition Would they want you to be specific? Carbon, Hydrogen, Oxygen and Nitrogen?

I thought a lot of biology was jabbering on :D Anycase I have the independant bio trial tomorrow Anyone else doing it?

Re: Trial exams.... Ugh, one thing, they should split the english exams up monday tuesday english tests are death

I have done English paper one and two Kill me

Yew! Chem of Art And! Im doing Quanta to Quarks in physics Anyone doing this combination of options? OMG it is heaven, they cross over so much!
