hhhhhhhhhhhhhhhhhhhhhh please i need the question

I have them but uploading here will take ages :/ give me your email address.

Dude the link i gave u has these things..

Not all of them, it only had the ones for electricity.

How are you supposed to use two rectangular blocks of wood and a rule to measure length in physics paper 6??

Q 2a) http://www.mediafire.com/i/?tlmavyawwhz811q
Q1 d) We'll have to take the L and H from 1.1 (coz it says so in the question) and we'll have to take y as 2.5 mm coz its the average of the two given possibilities for y.
Answer: 58 mm x 60 mm x 2.5mm = 8.7 milliliters
Q3 vi) Draw a line 90 degree to NN'. Just like you draw a normal.
Q5 a) Take another ruler make sure that the ends of it touch the bench (To ensure correct output) then measure both ends of the original meter rule. If the result of both measurements is same they're horizontal.

thank u soo much! but dear the one u attached file that diagram has similarity with the question aske d:/

place the substance wat the ques asks for between the blocks and using a clamp place the rule close to the blocks and record the reading

 

[Manobilly]

Place the test tube on the bench,take the blocks put them near to the tube than measure the length of blocks by a meter rule.

 

[kainat husain]

hun the question doesnot ask us to extend to CD , u r correct now for the next part join the end of this line to the normal (NN')

yess thx

thanks a lot

Exactly the diagram has to drawn the same but with the Correct SYMBOLS not drawing like in the question. That is that simple

no dear u have miss understood 2a for the previous paper

2a for this one

is this wat ur askin?

 

[Dsilentkila]

which variant?

variant 1

 

[kainat husain]

is this wat ur askin?

thank u so much for ur effort but still m confused! look the drawing above it is totally different :/! and they r askin for additinal lead what do they mean :/

np ,
It means that u have to use another connecting wire to connect 'A'and 'D'
the resistors are A-B ,B-C & C-D <-- 3 resistors that i made in the drawing ,then as they say to connect A and D i connected A and D with a connecting wire (lead) in parallel..

 

[thats_me]

one lil question .
M/J 2010, q4, b(iv) onwards.
i dont get it.
Thanks in advance

biv: thita is given in bi ,it is 10 and u found 'a' in bv i got it 21 so 21-2(10) =1
c : statement: YES!
justify : Its with in the limit of accuracy as the diff we got is 1

i don't understand the question and the mark scheme's answer so plzzzzz help guys

ok u

ok u have mad eit parallel? how will we knw if we have to make parallel or not?
and the wires are slanting in circuit 2? we dont have to draw like tht?

It is to avoid parallex error we need to view the line directly in front of the card
Parallax error happens wen the line of eye sight is not perpendicular/vertically above tthe pointer
