Abungee cord with a spring constant of 800 stretches 6 meters at its greatest displacement. how much elastic potential energy does the bungee cord have? the bungee cord has 9600 ⇒ 14,400 j of elastic potential energy.

Elastic potential energy is given by formula

here we know that

Now using above formula we have

So elastic potential energy in the chord is 14400 J

it is called kinetic energy

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.
