When sound travels through the ocean, where the bulk modulus is 2.34 x 10^9 n/m^2, the wavelength associated with 1000.0 hz waves is 1.51 m. 1) calculate the density of seawater. (express your answer to three significant figures.)

1.03×10³ kg/m³

Explanation:

β = Bulk modulus = 2.34×10⁹ N/m²

f = Frequency = 1000 Hz

λ = Wavelength = 1.51 m

ρ = Density

Speed of the wave

v = fλ

⇒v = 1000×1.51

⇒v = 1510 m/s

Speed of sound

Density of seawater is 1.03×10³ kg/m³ or 1.03 g/cm³ (rounding)

the entire statement is true and correct.  

there's no diagram, nothing is illustrated, and no question is asked.

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.
