If concentration is 0, absorbence must be zero. I dont see how it can work any other way. My teacher penalised students in an assessment for not having AAS graph pass through (0,0)

line of best fit wont always work for AAS, this is because the line has to pass through (0,0)

I did the same thing as you, i wrote part c in Booklet 2, luckily i alerted the markers when i looked below question C and saw the instruction... The head supervisor told me it was fine, however he signed his initials on booklet 1 and wrote instructions for the marker that i attempted question...

Re: General Thoughts: Physics 5 is C 7 is b 8 i got D, not too sure 10 i put D, i assumed it was the wrong way around the ratio was 10:1 11 i put D 14 is B 15 is B 16 is A 17 is B 18 C? 20 is B

Fair Exam

B6 ~75, B5 ~65, the exam certainly wasnt hard, it didnt test any of the hard concepts only the basic ones most students should know but may not of been able to apply to the situation given in the Q. Fair exam IMO

Yes you are correct, essentially there will be still eddy currents produced in R, however they are minimal and there will be no observable difference in this situation

hope you get well soon, gl

Just some basic 2mark Questions: 1. Explain what is meant by drift velocity 2. Outline the photoelectric effect

For a transformer to operate there must be a changing magnetic field in the primary coil to induce a current in the secondary coil, as AC electricity has fluctuating magnitude and direction it is preferred as the input current for transformers as energy can be stepped up or stepped down more...

Yeh, apparently there is a lot of "ways" he measured wavelength some textbooks say he reflected the reciever wave onto a mirror and was then able to calculate the wavelength others say that he connected the detector and receiver loop with a piece of wire and then rotated the receiver loop to...

wow thats a killer, i dont do Legal but i assume its a lot of memorising, GL tomorrow

most the difficult multiple choice Qs are for motors, Success One really helps =D, Anways Question: Outline how Hertz was able to measure the speed of radio waves and how they relate to light waves (3marks)
