A double incline plane is shown below. The coefficient of friction on the left surface is 0.3, and on the right surface 0.16 . Calculate the acceleration of the system 2.83 ms

0.83 ms

0.65 ms

2.25 ms

which three statements are true about all alloys?

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.
