In the space, show how you use measurements and calculations to predict the final angular speed of the two-disk system? Hint: Be careful when measuring the diameter of the small disk. When the small disk is held above the large one, it is closer to the camera and appears to be larger than it actually is. Measure the size of the smaller disk after it is dropped onto the large one.

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.

when heated, the valance electrons increased their speed and transferred the heat from electron to electron.   i just took the test.
