Hi, I'm working on some coursework for which I have been modelling a curve to a set of points, and for the final section I am wanting to calculate how close each point is to the curve as a method of comparison between the curves I have calculated. Some of the curves are quadratic, and others are...

Hi, I'm thinking of doing an experiment related to Newton's law of cooling, just a simple heat up a liquid to a temp graph its rate of cooling, repeat for different liquids. I was thinking of seeing if from this graph I could calculate the specific heat capacity of the liquid, but I don't know...

Hi, So for a piece of maths coursework I am thinking of trying to calculate the surface area of an atom or molecule. I do not know whether it would be viable because there isn't a clear boundary for an atom/molecule due to the electron clouds. However I wanted to know if I could do something...

Maybe I should be referring to boiling rather than evaporation?

Hi I was thinking of doing an experiment for my maths coursework to plot a graph to, and was thinking of doing something related to the rate of evaporation of water. My thinking is that i conduct an experiment where I heat water to boiling point so it is at about a constant temperature with a...

Hi, Homework Statement I'm doing some research into the hydraulic jump and was wanting some help in calculating the impact force. Hydraulic jump is a phenomenon to do with the turbulence of the water - it is the 'ring' around the stream of water when a tap is turned on Homework Equations The...

Hi, I'm doing some research into the hydraulic jump and was wanting some help in calculating the impact force. The equation I have found to use is: F = m g h / s I have the mgh, and was wondering what to use as the slow down distance. If you didn't know what the hydraulic jump was, it is a...
