Thanks for the help Xiao :) Q1 seems to make sense now. For q2 I also thought it was carbonate at first xD, but eventually found out that its the test for phosphate.

Hello :) Two questions 1. This is from Conq. Chem, in a table of tests used to identify anions (p214 of latest edition). Anion: Phosphate Test: Addition of Mg2+ in ammonia, ammonium nitrate buffer produces a white precipitate of Mg(NH4)PO4. The given reaction for this test is PO4^3- + Mg2+ +...

Sure was, cheers for that :)

Hello This Q is from Dot point phys, http://img293.imageshack.us/img293/3829/imgpm4.gif I've figured that A, C, E, F, G, H have no induction as there is no change in flux, but i dont know how to work out the others :S the answers are: a: no induction b clockwise c no induction d anticlockwise...

ahh a solid.... thought it was aqueous xD Cheers :)

Ok so in we've reacted propanol with methanoic acid in the presence of H2SO4 and hopefully have some propyl methanoate somewhere there. We've taken away the sulfuric acid by neutralising with sodium carbonate, and taken away water by reacting it with calcium chloride. When water is reacted with...

Cheers jyu :)

Hi! Just a quick Q regarding banked circular tracks A section of the road is in the form of an arc of a circle of radius r. The road is banked at an angle (theta), so that a car of mass m travelling at speed v has no tendency to slip. Show that the resultant force on the car is given by...

Hello:) This refers to the dot point Students: perform an investigation to demonstrate the principle of an AC induction motor I've done basically the same prac as shown here http://hsc.csu.edu.au/physics/core/motors/2698/Phy935net.htm#net2 , but instead we turned a magnet blue-tacked onto a...

Ok, thanks everyone!

Ok I've got it now, cheers jyu :)

I'd also like to know how to this question :) [ex 9F q8 from patel btw]

Hey there :) I've done a thread search, but I still have some doubs about two different types of transformers and their efficiencies. 1. http://img145.imageshack.us/img145/2079/simpleij0.gif Now in this one, seems like sources of inefficiency arise from eddy currents in the iron coil...

Yeah, i better remember to include the m as part of the resistance lol xD. wow great explanation there ianc :D Thanks for the help guys :D

yeah that sounds about right lol xD. btw thanks for replying so early in the day :) I managed to obtain the answer with your equation, but how did you manage to obtain that eqn in the first place? my working comes out like this mg - kv² = mv(dv/dx) dx = mvdv/(mg-kv²) x = m int[v/(mg-kv²)dv]...

Sorry about the title lol, but here goes.. This question is in new senior mathematics, fitzpatrick 4U (page 165, q6), i just don't seem to get any of these resisted motion q's. "A particle falls from rest in a medium. If the retardation due to resistance in the medium varies as the square...
