PL HELP I'LL MARK BRAINLIEST Read the following list of objects: a coiled spring, a moving car, a falling stone, a flowing river, a boulder on top of a hill Which of the objects have only potential energy? (3 points) a A coiled spring, a boulder on top of a hill b A moving car, a boulder on top of a hill c A falling stone, a moving car d A flowing river, a moving car

 a moving car

flowing river

maybe the boulder on the hill if its moving

Explanation: poteoinal enrgry means something is moving sorry im not the bestat explaing things

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.

r = ρ x length / area  

ρ = r x area / length  

ρ is in ohm-meters  

in basic units, it is m³kg/s³a²  

i think this is it.
