A sea turtle has a mass of 860 kg. If the PE of the turtle is 20, 500J as it is being lifted onto a ship, how high above the water is the turtle?

h = 2.43 [m]

Explanation:

Potential energy is defined as the product of mass by gravity by height. In this way, you can calculate the height by means of the following equation.

where:

Epot = potential energy = 20500 [J]

m = mass = 860 [kg]

g = gravity acceleration = 9.81 [m/s²]

h = elevation [m]

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.
