There are four forces acting on the box: a spring pulls with a force of 40 n. the force of gravity acts downward; and the force of the table is pushing up on the box. what must be true of the frictional force if the box moves across the table?
a) it is equal to the effort force.
b) it is less than the effort force.
c) it is more than the effort force.
d) it is equal to the force of gravity.

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.
