8. [0.5/1 Points] DETAILS MY NOTES SERCP11 19.6.P.039. PREVIOUS ANSWERS ASK YOUR TEACHER PRACTICE ANOTHER A 5.50 turn circular coil of wire is centered on the origin in the xy-plane. The coil has radius $r = 0.225$ m and carries a counterclockwise current $I = 1.80$ A (see the figure below). HINT (a) Calculate the magnitude (in A \cdot m$^2$) of the coil's magnetic moment. 1.57 A current-carrying loop has a magnetic moment $\mu = IAN$, depending on the loop current, area, and number of turns. The magnetic moment is independent of any external magnetic field in which the loop may be submerged. A \cdot m$^2$ (b) Find the magnitude (in N \cdot m) of the magnetic torque on the coil due to a 0.300 T magnetic field that is directed at an angle $\theta = 57.0^\circ$ from the positive z-direction and has components only in the xz-plane. 0.228 N \cdot m Need Help?

14. If you were given the chemical structure of an R group, could you place it in the correct group? (LO 1.3). Study the amino acids in your text. Work on the R groups until you can see common elements in each category, and then summarize what is common to each category. We want to find patterns to help us predict whether R groups are. Knowledge of chemical bonds from Intro Bio (see question 4 earlier will be helpful!) Category Common Elements Nonpolar Polar Electrically charged
