Physics Oct/Nov 2010 P43 q3 (A) i - Help needed , And where is the freakin examin report ?

Since in the equation we have the amplitude as -4......and -4 corresponds to lowest postion........-4x2 the max height...=8

 

[kakarocks]

How is the amplitude -4? its says d=-4cos(220t)

FOR Chemistry PAPER 33!!!!!!!!!!

hydrated ammonim salt titrated with KMnO4
usual salt analysis
one thermal question

We have to titrate ammonium nitrate with KMn04 or would we need to oxidize potassium iodide in the presence of ammonium nitrate and then titrate the resulting solution with sodium thiosulphate? :|

see question no.1 in june2008-31
a similar question is expected!


FOR PHYSICS ASLEVEL PAPER 33

what we hav been practicing is the electricity one with beads in place of resistors.its very simple..and ya in the oscillation one we will be having a cylinder instead of a pendulam bob..

i doubt anything concerning magnets or diodes on A2 level will come for As practicals, hmm, they might just be giving diode as just another component of the circuit system, in past years there were things like that, but the procedure is still the same, you will just have to either measure current, volt etc. and draw the graph, and by the way it will be helpful to review the graphs for diodes. before going for exam.

YOU WILL NEED
1.retort stand.
2.bob/cylinder
3.stopwatch.
4.thread
5.multimeters
6.batteries
7.clamps.
8.resistors.
9.contacts

WEll ? i really have p4 tommorow and would appreciate any help X_X . And where is the EXAMINER REPORT i cant find it anywhere

 

[workinghard]

xamination report is here on forum under da topic about da w10 report search it u ll find it
plus amplitude is -4 because if u lok at general eq its d= do coswt!!
n do is amplitude which is -4 here
did i help u?

 

[kakarocks]

how could haave i forgotten that X_X I am ruined i guess . Thanks a lot . However i cant find the Examiner Report , could you give a link?
