Volume = length * width * height
length * width = Area = A
So Volume = A * height or A * h
Ah ah i see, hahaha thanks thanks

Yeah, that should be it. There is an alternate method, though, just in case you're interested:
Find the gradients of the steepest line that passes through all the error bars, and the shallowest line that passes through all the error bars.
Suppose they happen to be 5.7 and 4.3 in any units (and the gradient of the best fit is 4.0).
The calculation you carry out = 0.5 * (Gradient of Steepest line - Gradient of shallowest line)
In our example, this is 0.5 * (1.4) = 0.7 (in the relevant units).
So we'll write that the gradient is 4.0 ± 0.7.
The marking scheme from a 2012 October/November paper probably puts this best:
"Uncertainties in Question 2
(c) (iii) Gradient [U2]
Uncertainty = gradient of line of best fit – gradient of worst acceptable line
Uncertainty = ½ (steepest worst line gradient – shallowest worst line gradient)"
So really, either method is accepted as long as you make it clear which one you are using.
Good Luck with all your exams!
This is from paper 1...and the answer is v=underoot (g x lambda)...but HOW?Which formula could be correct for the speed v of the ocean waves in terms of the density p of sea water, the acceleration of free fall g, the depth of the ocean h and the wavelength, lambda?
Always use rawPAPER5 doubts,
So for question 2, we obtained gradient and y-intercept, the questions after that, are we suppose to use raw gradient and y-intercept in calculations, or the round up gradient and y-intercept? Thanks guys!

If u Convert Quantities into Base Units.. The Check If Right Hand Side Equals LEFT hand Side..! If it does then Equation is true And Valid..! If u Couldn't The I would Explain Further !This is from paper 1...and the answer is v=underoot (g x lambda)...but HOW?
POT is actually power of ten error.what is the word POT mean i am sick of seeing this in every paper
meaning???POT is actually power of ten error.
What does FOX mean any idea I've seen that as well in P5 ms ??.
so that magnetic field lines are evenly spread outThis is of paper 5
when we throw a magnet in a vertical coil , how to make the speed uniform in all parts of its vertical motion? The markscheme says -
1.Use of short magnet so that v is (nearly) constant
2. Use short/thin coil so that v is (nearly) constant
WHY? HOW?
Are u asking me what FOX means then I have no idea either it's pretty annoying it normally in ms is in the answer for y intercepts so I guess it's ant using false origin axes like they don't use origin on graph for at least x axis and u read the graph at this point thinking it's the y intercept so then u do FOX error I guess.meaning???
Don't have time will help with 4 .
what ?!table me uncertainities nikalnay ka kia formula hai ?
