Determinar la dirección de la aceleración del centro de gravedad del eslabón mostrado. El cual tiene 10 pulgadas de largo, 4 lb, es perfectamente simétrico, en el punto P actúa una fuerza externa de 40 lb y su inercia de masa de su CG es de 0.08 lb-pulg-s2. Además, sus datos cinemáticos son: θ
2 = 25 grados,
ω
2 = 25 rad/seg,
α
2 = 25 rad/seg2.

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.

i think the answer is a, hope this : )

a sonic boom is a loud boom that breaks the sound barrier

explanation:

the components of a vector are the parts of the vectors that are to each other.

b perpendicular
