A car of weight 2270 N operating at a rate of 126 kW develops a maximum speed of 39 m/s
on a level, horizontal road.
Assuming that the resistive force (due to
friction and air resistance) remains constant,
what is the car's maximum speed on an incline
of 1 in 20; i. e., if 0 is the angle of the incline with the horizontal, sin theta= 1/20
Answer in units of m/s.

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.
