You are launching a 2 kg potato out of a potato cannon. The cannon is 1.1 m long and is aimed 60 degrees above the horizontal. It exerts a 46 N force on the potato. What is the kinetic energy (in J) of the potato as it leaves the muzzle of the potato cannon/.

the plateau is likely to turn into a desert do to corrosion.

the answer is b ) square root of 5

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.
