(a) the cartesian coordinates of a point in the xy-plane are (x, y) polar coordinates of this point. (-3.11, -2.05) m. find the r3.724 m e=-33.4x your response differs from the correct answer by more than 10%. double check your calculations. (b) convert (r, e) = (4.86 m, 38.70) to rectangular coordinates. y= exercise hints getting started i'm stuck! (a) find the polar coordinates corresponding to (x, y) = (3.1, 1.63) m. 3.50 m (b) find the cartesian coordinates corresponding to (r, e) (4.2 m, 59°).

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.

what experimental evidence led scientists to change from the previous model to this one?

a few of the positive particles aimed at a gold foil seemed to bounce back.

the colors of light emitted from heated atoms had very specific energies.

experiments with water vapor showed that elements combine in specific proportions.

cathode rays were bent in the same way whenever a magnet was brought near them.
