The graph describes the motion of an object.

the object moves from a to b. from b to c. it moves from c to d.

1.constant acceleration, constant velocity, positive acceleration

2.remains stationary, slows down, speeds up

3.constant accelration, constant velocity, positive acceleration

another example of kinetic energy would be,

kinetic energy   >     moving energy

answer   >   letter choice (c),   a hammer falling off a table.

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.

no

explanation:

no i dont know how to solve this you should probably try to google the answer
