On a smooth, level surface, a red marble with a mass of 0.02 kg is moving with a velocity of 2.0 m/s. The red marble collides with a yellow marble of equal mass that is at rest. After the collision, the red marble stops completely and the yellow marble is now moving in the direction that the red marble was moving. Based on the information given above, choose the best conclusion.
A
The yellow and red marble have the same momentum before colliding
B
The red marble has more momentum than the yellow before colliding
C
The collision doesn't matter when it comes to momentum
D
The yellow marble moved with half the speed of the red marble

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.
