Consider a uniformly charged ring in the xy plane, centered at the origin. the ring has radius a and positive charge qdistributed evenly along its circumference. a)what is the direction of the electric field at any point on the z axis? . b)what is the magnitude of the electric field along the positive z axis? use k in your answer, where k=14ĻĻµ0. d)the ball will oscillate along the z axis between z=d and z=ād in simple harmonic motion. what will be the angular frequency Ļ of these oscillations? use the approximation dāŖa to simplify your calculation; that is, assume that d2+a2āa2. express your answer in terms of given charges, dimensions, and constants

4. now look at the green lines you created by connecting the three boiling point data points and the three melting point data points. for each of these lines, describe any trends you see. 5. locate the elements on your periodic table that you circled in green on your graph. what term or description would you use to identify these elements with respect to the periodic table? 7. using the room temperature line (orange line) and your periodic table, make lists that identify the state of matter (gas, liquid, or solid) in which each element you plotted exists at room temperature. explain your answers.
