A positive point charge q is placed at the center of an uncharged metal sphere insulated from the ground. The outside of the sphere is then grounded. Then the ground wire is removed. A is the inner surface and B is the outer surface.
Which statement is correct?

A. The charge is –q/2 on both A and on B.
B. The charge on A is –q; there is no charge on B.
C. There is no charge on either A or B
D. The charge on A is –q; that on B is +q.
E. The charge on B is –q; that on A is +q.

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.
