An ultrasound pulse has a wavelength of 1.0mm. its speed in water is 1400m. what’s the frequency?

Explanation:

The relationship between the frequency, the wavelength and the speed of a wave is given by the wave's equation:

where

v is the speed of the wave

f is the frequency

is the wavelength

For the pulse in this problem,

Solving for  f, we find the frequency:

grav potential energy

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.
