Great job congratulations :) I got 4A*s in A Level

Well yes if you are passionate enough. The add maths syllabus is less than maths syllabus

If you are very good in maths and have gone through it already then doing add maths in this time won't be too difficult

X coordinate in the last part wasn't this, it was greater then 1...the diagram clearly showed that it had to be between π/3 (the upper boumdary calculated for area in the previous part ) and π/2

So if you do by this method, the mean time is 9.4±0.1s so isn't max value 9.41 and min 9.39? Error in T will then be 0.005 And if we apply the other rule that if a quantity is being multiplied or divided by a number, then the error in the calculated quantity is error in previous quantity times...

What was the error in T?

Ok thank u so much! Just a little thing, we need the intensity of sound wave before reflection as well as mentioned in the formula so I think that needs to be measured as well

And plz tell me how will the intensity be calculated from the amplitude. Amplitude² is proportional to intensity but how will the value be calculated as we don't know of any constant in this equation. P.s should't the microphone be placed beside the speaker with a barrier in between? And to...

If anyone has drawn diagram for this, plz share

I think it's not important to show the pump specifically, we can just show a tube and write 'to pump' and yes a pressure guage instead of the manometer which will be shown as a circle and labelled. Manometer will also work but then we need to explain it in detail that how value for pressure will...

Thank you! :)

Thanks :) A pump should also be placed to vary pressure

Plz someone help with this...how is the diagram drawn? It's w18 p51
