An 8.50 kg point mass and a 13.0 kg point mass are held in place 50.0 cm apart. A particle of mass mm is released from a point between the two masses 18.0 cmcm from the 8.50 kg mass along the line connecting the two fixed masses. Required:
Find the magnitude of the acceleration of the particle.

ok

explanation:

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.
