Plant growth the growth rate of a tree is predicted by g = in( " +b+c) where m is the age of the tree, g is the growth, and a, b and c are constants. a m2 m scientist perform an experiment and measured the following data points mexp = {2, 5, 10, 15, 20, 25, 30, 35, 40} months and gexp = {5.7,41., 3.3, 2.5, 2.1, 2.2, 1.7,1.6, 1.3} centimeters. write a function plantgrowth to calculate the coefficients a, b and c by using regression given experimental datasets mexp and gexp and estimate the growth of the plant at a given month. restriction: the function plantgrowth must use polyfit. hint: linearize the dataset before performing a polynomial fit.

An array of m-50 thermoelectric modules is installed on the exhaust of a sports car. each module has an effective seebeck coefficient of sp of 0.143 5vk and an internal electrical resistance of r.-4 ? in addition, : (15 points each module is of width w 60mm and contains n=100 pairs of semiconducting pellets. each pellet hasan overall length of 2l-5mm and a cross-sectional area as 1.2 x 10'm and is characterized by a thermal conductivity of kpl2w rnk. the hot side of each module is exposed to exhaust gases at·p650c with hia4ow rrk while the osite side of each module is cooled by pressurized water at surface) and 156 °c (at the cool surface). 11s c with h: -500w/m'k. the modules are wired n series and the load resistance is r d=400ohm .the module surface temperatures, t, and ts are 183 "c (at the hot surface and 156c (at the cool surface) a)-draw a schematic of this scenario and label all parts. a. b. if the induced current, i, is 0.15 amps, what is the total power (pa) for one module? c. what is the total power harvest from the exhaust with all 50 modules?
