Hey.Do we have to make crosses when drawing a graph or can we just draw dots with circles around them?

And do we have to pass our lines through the origin?

Not always... depends on the points that you plot. For each experiment there are different points so the lines will be different. Sometimes the line may even pass through the negative part of the y-axis to give a negative y-intercept.
I think you need some practicing of the question papers o_O

Yes I have practiced a few papers and I get it now :) Thank you.

hey guys in n07 to measure pressure we are using pressure gauge. it's saying not allow pressure meter or barometer. so in calculating pressure do we always use pressure gauge or sometimes pressure meter or barometer can be used. help plzz :)

Awww okay thank you very much :)
hey in n07 to measure pressure we are using pressure gauge. it's saying not allow pressure meter or barometer. so in calculating pressure do we always use pressure gauge or sometimes pressure meter or barometer can be used. and in mark scheme there is a pt written difficulty in measuring amplitudes at small pressures. Use a large incident source. So i wrote that use high values of p so that a could be measures easily. So can u explain this mark scheme point. And another point that the window should be perpendicular to source. Should we write this point whenever something is being transmitted through a substance? And what is the purpose of the pt. these are a lot of questions sorry but plzz help :)

Hey
This diagram is by geek101 , hope it helps

on:07 (A).JPGon:07(B).JPG

I think yes we have to write those for all questions involving transmission
Sorry i can't be quite elaborate, haven't gone through that paper yet.

can any one plz help on these 3 QS
1. SHOULD THE NO. OF SIGNIFICANT FIGURES BE THE SAME THROUGHOUT A COLUMN OR THE NO OF DECIMAL PLACES?
2 THE NO OF DECIMAL PLACES OF AN ERROR SHOULD ALWAYS BE EQUAL TO THE NO OF DECIMAL PLACES OF THE QUANTITY IN WHICH THE ERROR IS?
3. SHOULD GRADIENT AND FOLLOWING CALCULATIONS ALWAYS BE IN 3 SIGNIFICANT FIGURES OR DOES THAT DEPEND ON THE VALUES PLOTTED
Ill be very grateful ...

not sure abt the first one. but i think that depends on the values given.
if the values given are in decimal points, then the calculated value shud have the same no. of decimal points.
and if it is not in decimal points, then the calculated value shud be in the same no. of sig fig.

2) yes the error shud have the same no of decimal points/sig fig.

3)that depends on the values u have taken.

Hope i helped.

abt the amplitude part when u do that question please reply. and i wanted to ask in measuring pressure should we always use pressure gauge or at some instances barometer should be used.
