Physics P22, How was it!

guys i found the power directly from the resistors , so if the resistors were in parallel which is half the power was double.. hope thats correct , i did that and found the ratio i forgot what the ratio was -_-

I think that wont work

ration 3:5?
and pd 3.2?

ration 3:5?

and pd 3.2?

Not sure about the p.d but ratio was 3:5

Any one sure about the pd across C and D for the electricity question????.....i got 11.2V

most of us got either 4.8v or 3.2v.. dno which is correct

um remember the last question on the last page? how did u find the energy?

the last page , last question what was energy? or apkay grades last year kyaa tayh?

You convert Mev to joules and then do 60 divided by that answer...

It was a disaster for me :'(

max C grade! :'(

Dont worry most of the candidates found it tough than the previous past papers
Percentile would definately be low around 34-35 for A grade

11.2?? dont u think that too much for 12 v supply?

i got 3.2

yeah must be 3.2 then coz most of the people got that......What did you write for the arrangement of atoms in metals, polymers and amorphous solids in the 3rd question?

 

[terry jefferson]

Does anyone know the answer to arrangement of atoms in metals, polymers and amorphous solids in the 3rd question?

Solids -regularly arranged closely packed
Polymer-Long chain of small molecules know as monomers
amorphous- irregularly arranged not closely packed
