Required information The rate of absorption of radiation by metal plates varies with the plate thickness and the nature of the source of radiation. A test was conducted at Ames Labs on October 11, 2005, using a Geiger counter and a constant source of radiation; the results are shown in the following table: Plate thickness, W, mm Counter, C, counts per second 0.20 5500 5.00 3720 10.0 2550 20.0 1320 27.5 720 32.5 480 \\ Using computerassisted methods, find the coefcient and the exponent of the exponential function that best t the data. For the exponential function. the best t for the data is C(countsfsec) = 5358.28 e "ODDS W(mm)_
