Blocks A and B of masses mA and mB , respectively, are attached to an ideal pulley to create the Atwood’s machine shown in the figure. Which of the following free-body diagrams could be correct for the blocks when they are released from rest if mB>mA ?

its c i just checked it

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.

i think the answer is tomato juice? not entirely sure though
