chemistry and physics 31,33,34

[Pinky]

Okay any idea about physics paper 32 ?? :S

 

[Sabrina]

in p33,i think u will have to find the terminal velocity using oil and glass balls of different size...
and something related to diode and dc power supply.

can any one please confirm whether its a LED or LDR because i have heard none of them is coming its just simple diode.

 

[ashgerrard]

what is p31 going to have in electricity section
is it a normal paper or does it have wierd questions?

 

[bilal_92]

hey what abt p34?? that prism thingy instead of pendulums

 

[taha]

ive never done ne practical on oil viscosity b4....wat is it abt???ne resource....is da diode part ov q1 or q2???

 

[rethna30]

@Taha...


I googled for the oil viscosity experiment and found some good examples...have a look...

You can refer to

9702_s07_qp_5.pdf
and it's marking scheme

i think no1 would have ever done that practical..=s///
but i dont think it ll be that tricky...=/

 

[Glowing light]

not be that tricky*

i am not sure about what exactly is going to come in prism one. u will be given a rod, strings and prism. u might have to find out the extension too.

hey rehana30!!!
thnx for dat reference to da marks scheme!!!!
it ws vry vry helpful!!!!!

btw ru a teachr or alvl studnt urslf????

 

[ashhadazam]

Any guesses on cations anions .. ? Chem 34 ??

 

[wadha]

can u plzz tell me details abt pendulum wht in phy p31
can u explain more abt it in detail
plzzzzzzzzzzzzzz
thnxs in advance

simple....u take da pendulum...

1.measure da length.
2.take it to 1 side.
3.give it a swing.
4.be4 tth strt ur stopwatch.
5.aftr N.no.of swings.
6.stop ur stopwatch.
7.divide time taken by N.
8.then play around with ur pendulum with different lengths.

hope tht helps... :mrgreen:

 

[ashhadazam]

That definitely was enlighjtening !!! BUt swinging prisms seems too much of fun !

 

[ashhadazam]

Cations anions someone ? :S

 

[bilal_92]

@sabrina:thnx but hw r we gonna calculate da tension???what kinda experiment will it be???

 

[WellWIshER]

That definitely was enlighjtening !!! BUt swinging prisms seems too much of fun !

oooh LALALA....u got prisms.....well...

in tht case..ASK MR.GOOGLE :mrgreen:

but dont swings prisms....u might loose control and then da prism might hit da invigilator and then....______welll :lol: :lol: :lol:

 

[ashhadazam]

And then well.. ahahahah !!! Mr.Google is quiet these days !! but still.. thats the fun part isnt it ? Smashing the prism etc etc D:

indeed..i cant wait to see da invigilators...eye POopin out :mrgreen:

but da consequences..are a BIT costly.....

we will JUST be disqualified from ALL exams: :mrgreen:

 

[wadha]

can u explain in detail abt phy p31 pendulum all abt
thnxs
plzzzzzzzzzzzzzz
