Where B represents additional counts due to background radiation. Plot the followingdata on a suitable graph and test this hypothesis.ДЇorce (mN) : 0:1 0:15 0:2 0:25 0:3 0:35 0:4 0:45 0:5 0:55 Current (A) : 2:6 3:08 3:75 4:3 4:74 5:36 5:64 5:67 6:29 7:0 Д¤.) The number of counts measured from the decay of a radioactive isotope in thelaboratory is described by the equation When the two currents are equal, we expect F to be proportional to I2. Which, in your opinion, gives the better t? If this wasdata from one of your experiments, how would you decide which result to use? Determine the slope, intercept and theiruncertainties. Memorial University of NewfoundlandDepartment of Physics and Physical OceanographyДЎ.) Fit the following data to a straight line.

Most of the data that you obtain in the laboratory will consists of pairs of (x,y) values,for example: Reading data from a laboratory experiment The graphs which you obtain will, usually, be one of the following forms:ДЄ) straight line f (x) = mx + bb) simple polynomial f (x) = a + bx + cx2 + c) power law f (x) = Axnd) other functions not described by any of the aboveIt is good practice to reset everything before you begin a Mathematica session: This is a shortened version of the document, Graph Plotting and DataAnalysis using Mathematica, which you should read for a more complete descriptionof Mathematica plotting commands. The purpose of these notes is to show how Mathematica can be used to plot and analyzelaboratory data.
