Wis the work done on the system, and k, u, and eth are the kinetic, potential, and thermal energies of the system, respectively. any energy not mentioned in the transformation is assumed to remain constant; if work is not mentioned, it is assumed to be zero. part a select a specific example of a system with the energy transformation shown. u→δeth select a specific example of a system with the energy transformation shown. a wood block sliding across a rough horizontal surface and slowing to a stop. a wood block moving across a horizontal rough surface at constant speed. a wood block sliding down a rough inclined surface at a constant speed. a block sliding on level ground, to which a cord you are holding on to is attached.

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.

a. are

jupiter is the largest planet in our solar system, having a mass and radius that are respectively, 318 and 11.2 times that of earth. suppose that an object falls from rest near the surface of each planet and that the acceleration due to gravity remains constant during the fall. each object falls the same distance before striking the ground. determine the ratio of the time of fall on jupiter to that on earth.
