Edit: sorry, fixing up latex. Thanks for responding. Given that each channel has been measured independently of the others, the counts in each channel f(y)\pm \sqrt{f(y)} can be used in the "simplification method". To expand on the definition: y_F = \int_{0}^{\infty}yf(y)dy = \Delta y \sum_{i...

Homework Statement Based on Microdosimetry theory, trying to figure out error propagation for a lot of quantities that are produced from radiation spectra. I am having trouble finding information on how to calculate and propagate errors when the quantities in my equations are not independent...

Hi there, So I am doing this lab write-up at the moment with a single channel analyser. The following diagram pretty much sums up the setup: So pretty much I have found a suitable operating voltage gain by recording number of counts vs. gain and now I must change the Baseline-E...

Yeah I have done this (I sent you a pm before?). I was just explaining.

Charles’ Law describes the volume of a fixed quantity of gas maintained at constant pressure is directly proportional to its temperature. When the valve has not been released the bag has a fixed volume so I don't think you can just set the temperature to 1 (essentially cancelling it) as this...

Even though the temperature is constant, you do not know it ---> I do believe you cannot find the number of molecules or the number of moles as both of these are dependant upon temperature.

Could you explain in greater detail how to do this question, anyone?

Homework Statement 1. Consider ideal gas in a rigid cylinder of 2 litres, at pressure of 3 Bar. The gas is connected through a thin capillary to a free expanding bag, which contains ideal gas at pressure 1Bar and volume of 1 litre. A valve in the capillary initially prevents the gases to mix...

Thank you for replying :) Yes but they are two formulae that show the same thing - surely there should not be any anomalies with the data if it is all consistent? What I mean is, it shouldn't matter how many significant figures - it should all work out shouldn't it?

Homework Statement I have been given Planck's Radiation law and Wien's Law, and need to say whether the values produced from both are the same or different. Homework Equations Planck's Equation: Wien's Law: The Attempt at a Solution So, I have completed the task of...
