If the equation of motion of a particle is given by s = b cos(ωt + δ), the particle is said to undergo simple harmonic motion.

(a) find the velocity of the particle at time t.

(b) when is the velocity 0?

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.
