A1.0-kg block and a 2.0-kg block are pressed together on a horizontal frictionless surface with a compressed very light spring between them. they are not attached to the spring. after they are released and have both moved free of the spring
the lighter block will have more kinetic energy than the heavier block.
the magnitude of the momentum of the heavier block will be greater than the magnitude of the momentum of the lighter block.
the heavier block will have more kinetic energy than the lighter block.
both blocks will both have the same amount of kinetic energy.
both blocks will have equal

Selma made a diagram to compare convection and radiation. which label belongs in the area marked x? must involve temperature differences between substances or objects only occurs when molecules are in direct contact involves the movement of fluids based on density differences can occur where there is little or no matter

The combining of light nuclei is called blank. blank as in not actually blank. you know what im tryin to say.

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.
