May 2007 Q3 b part
We are currently struggling to cover the operational costs of Xtremepapers, as a result we might have to shut this website down. Please donate if we have helped you and help make a difference in other students' lives!

Sorry i forgot to mention P4bi) mass unit is kg.
A is m^2
rho is kgm^-3
h is m
so A * rho * h = kg = mass.
ii)
pressure = force / area.
pressure = mass * g / area
pressure = A*rho*h*g/A = rho*g*h
3b)Sorry i forgot to mention P4
Thank's a bunch.3b)
Count the number of squares to get the area. I got 21cm^2.
now u should calculate the pd represented by 1cm^2.
1cm^2 = side2 x side2
= (2.5 x 10^3) (1 x 10^-2)
= 25 V
now multiply the total are u calculated first (21 cm^2 ) into 25V
21 x 25 = 525 V
thank u
I have this.does anyone know a website that has classified past papers for physics
That's impossible, both in terms of how long and hard the papers are and the distance from the minimum for A. Even after memorising the whole textbook my marks while practising barely come up to A, how do you think one goes about achieving an A*?I would assume less than 10 marks lost for each paper.
Well, my advice is to do really well for your AS exam. Aim for the paper 3(practical). And its actually not impossible to score less than 10 wrongs for the paper 1 & 2. (Totally possible!) Just practice more and remember that physics is about application not memorizing.That's impossible, both in terms of how long and hard the papers are and the distance from the minimum for A.

thanksI have this.
Well in A2 far too many questions require huge amount of memorising and the few calculation questions are always worded annoyingly, I hate CIE. Btw I'm repeating AS level so this year I haven't attended a single AS practical class, what do you think I should do now?Well, my advice is to do really well for your AS exam.

Do practicals... grasp techniques as much as u can... n good luckWell in A2 far too many questions require huge amount of memorising and the few calculation questions are always worded annoyingly, I hate CIE.

For almost 10 years, the site XtremePapers has been trying very hard to serve its users.
However, we are now struggling to cover its operational costs due to unforeseen circumstances. If we helped you in any way, kindly contribute and be the part of this effort. No act of kindness, no matter how small, is ever wasted.
