A piece of putty of mass m = 0.75 kg moves at a velocity of v = 2.5 m/s along a horizontal frictionless surface. It hits and sticks to the bottom of a rod of mass M = 2 kg and length L = 0.9 m which is held by a frictionless nail at the opposite end of the rod, as shown. a) Find the frequency of the subsequent oscillations.
b) If the putty had hit and stuck to the rod at a higher point, would the rod-putty system oscillate faster or slower?

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.
