What could explain this observation? As the holding height increases, What could explain this observation? As the holding height increases, the moment arm of the rope about his feet decreases due to the angle that his body makes with the vertical. a smaller tension in the rope is needed to produce a torque sufficient to balance the torque of the weight about his feet. his center of mass moves down to compensate, so less tension in the rope is required to maintain equilibrium. the moment arm of the weight about his feet decreases due to the angle that his body makes with the vertical.

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.

god i hope this !
