The same force f is applied to the edge of two hoops. the hoops have the same mass, although the radius of the larger hoop is twice that of the smaller one. the entire mass of each hoop is concentrated at its rim, so the moment of inertia is i -mr2, where m is the mass and r is the radius. which hoop has the greater angular acceleration, and how many times as great is it compared to that of the other hoop?
the larger hoop; two times as great.
the smaller hoop; two times as great.
the smaller hoop; four times as great.
the larger hoop; four times as great.
both have the same angular acceleration.

ok

explanation:

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.
