Two students are practicing hitting baseballs off of a tee. The first student says the baseball has the same amount of inertia regardless of how hard you hit it, but it will accelerate twice as fast if you hit it with twice the force. The second student argues that it will accelerate twice as fast if you hit it with twice the force, but says the ball that is hit harder will have twice the inertia. Who is correct, and why?
A. The first student is correct, because inertia describes an object’s resistance to change in motion with respect to its amount of mass only.
B. The second student is correct, because inertia describes an object’s resistance to change in motion with respect to its amount of mass and speed.
C. The first student is correct, because inertia describes the energy that an object contains when it is not moving.
D. The second student is correct, because inertia describes the energy that an object contains, and objects that are moving have more energy.

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.

Point charges q1=+2.00μc and q2=−2.00μc are placed at adjacent corners of a square for which the length of each side is 1.50 cm . point a is at the center of the square, and point b is at the empty corner closest to q2. take the electric potential to be zero at a distance far from both charges. part a what is the electric potential at point a due to q1 and q2? express your answer with the appropriate units.
