Hey.Do we have to make crosses when drawing a graph or can we just draw dots with circles around them?
I'm afraid crosses aren't allowed :/
You have to plot tiny and clean dots with circles around them

Really? That is great then I hate making crosses.
And do we have to pass our lines through the origin?
Are you sure about that?? :O I didn't see it specified in the syllabus :/
Yes I have practiced a few papers and I get it now Thank you.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
My teachers in school always told me to plot neat and tiny dots
I dont know, maybe it is allowed... But I have been taught not to draw crosses
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 helpAwww okay thank you very much

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 ...
Hey
This diagram is by geek101 , hope it helps

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.
and can u upload other diagrams as well so that i can tally my diagramsHey

anyone did the graph portion ov this one? and the errors one too obviously ?
can anybody show the graph plotted or the errors ?
