Sorry have no idea But i still its just a guess that's the reason in the marking scheme they have given a wide rage

No problem .

T is the height

But T was the thickness which in no way is related to height :/

 

[ZaqZainab]

When it says draw a ray to the left of the normal
do we draw it on the left or right i used to think right as t says TO the left means goes to the left but i am slightly confused

Yeah it's weird but in this question it's the height .

ANYONE ?

You're supposed to estimate the mass of the ruler. It says "The student chooses a mass M which is similar to the mass of the metre rule". You're supposed to be able to estimate the mass of a metre rule. That's why they gave such a large range

Thank you , do you think that i should do the variants ? doesn't it enough to do my region papers ?

Np I certainly think doing the variants will be really helpful. It'll give you a wider range of questions to answers, but try your own region's papers first. Gl for your IG's

Okay , I will thanks

Btw everybody. This is probably not that important, but for physics paper 6, typically the first question don't forget to write down the column heading

Q 1 C ,, I got a straight line in the graph so i can find the gradient by Y2-Y1/X2-X1 , but why in ms they say show a triangle ?

Q 1 D : what is the value of G ? and how ?

Q 3 C : whats the answer and explain please ?

+ Can I have a tip in choosing the scale of a graph when having decimals valus ?
Thanks in Advance !

For http://papers.xtremepapers.com/CIE/Cambridge IGCSE/Physics (0625)/0625_s12_qp_62.pdf question 1d) would using a string attached to a ball bearing and comparing it to the marks on the rule be a suitable answer?

how to draw circuit diagrams in paper 6 physics? where should i place voltmeter and ammeter n stuff? :S someone please help

Voltmeter parallel and ammeter series .

I think measure the distance between the 1st end of the meter rule and the bench , and measure the distance between the 2nd end of the meter rule and the bench , if they are = then it's horizontal , but could u check mark scheme please for it ?

I did that's the right answer. Was just wondering if pendulum would also work. Probably not since my answer's not in the mark scheme. Thanks

thanks alot!

 

[Lightning soul]

thanks alot!

Np always happy to help

 

[fatimanasir]

and how to calculate paper 6 oct/nov 2009 question 1(ii) the t2/s2 question?

 

[GorgeousEyes]

thanks alot!

anytime
