Part F For both Tracker experiments, calculate the average vertical acceleration, where the time period is t = 0.10 second tot = 1.00 second. Consider
only the magnitude of the vertical velocity in the calculations. Record your results to three significant figures.
Comment: How does the average acceleration of the two balls compare to the theoretical value of -9.81 meters/second, and how do the
accelerations of the two balls compare to each other?

answer;

d. are made mostly of liquid

explanation;

-the general   composition and structure planets includes; they have a thick gas and liquid layer covering a small,solid core. mostly the gases are hydrogen and helium atmosphere and layers of liquid hydrogen. for instance neptune and uranus are examples of the outer planets, they have a core covered by ice and ammonia.

-neptune's atmosphere is hydrogen and helium with a bit of methane so there is no oxygen to breath and the interior is made up of frozen water and ammonia with a rock and iron core. thus, there is no liquid water or solid surface to survive.
