A harmonic wave is traveling along a rope. It is observed that the oscillator that generates
the wave completes 38 vibrations in 33.8 s.
Also, a given maximum travels 443 cm along
the rope in 10.7 s.
What is the wavelength?
Answer in units of cm.

are there answer choices to this question? this seems like a question where you have options to choose from.

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.
