8. A conducting circular loop made of wire of diameter d, resistivity $\rho$, and mass density $\rho_m$ is falling from a great height h in a magnetic field with a component $B_z = B_0 (1 + kZ)$, where k is some constant. The loop of diameter D is always parallel to the x-y plane. Disregarding air resistance, the terminal velocity (in mm/s) of the loop is: (assume g to be uniform) (Given ; D = 1m, k = 2T/m, $B_0$ = 2T, $\rho$ = 1.72 $\times$ $10^{-8}$ SI unit, $\rho_m$ = 8.96 g/cc)

Consider the following dataset which contains Years of Education and Number of Protests in the previous 12 months for a sample of 5 individuals. You will study the impact of education on protest participation. Education in Years: 12, 6, 14, 16, 20 Number of Protests: 6, 12, 4, 3, 2 Make a scatterplot (by hand) of the dataset. Now, using the same dataset, calculate the correlation coefficient, r-squared, regression slope, and intercept. If you have a new respondent in your survey who has 20 years of education (PhD in Poli Sci), what is the predicted number of protests according to your regression? Continuing with the previous question about predicting the number of protests for an individual with 20 years of education: Show your calculations. Does this prediction seem reasonable? Why or why not?
