P waves are faster than S waves and surface waves.
<h3>Surface waves</h3>
A surface wave in physics is a mechanical wave that travels at the interface of two different media. Gravity waves on the surface of liquids, like ocean waves, are an example that is frequently used. When two liquids with different densities come together, gravity waves can also form at that junction. Solid surfaces can experience elastic surface waves like Rayleigh or Love waves. The way that electromagnetic waves can be steered along a gradient in refractive index or at the boundary between two substances with varying dielectric constants is known as "surface wave" propagation. A guided wave that travels relatively close to the Earth's surface constitutes a ground wave in radio transmission.

To solve this problem it is necessary to apply Boyle's law in which it is specified that
Where,
and 
are the initial pressure and volume values
and 
are the final pressure volume values
The final pressure here is the atmosphere, then
Pressure at the water is given by,
Using Boyle equation we have,
Therefore the volume of the lungs at the surface is 5.9L
Is moving, i'm almost positive
Answer:
The new energy density is same as initial energy density u0 as it is independent of plate dimensions
Explanation:
As we know that energy density is total energy per unit volume
so we know that isolated plates of capacitor is placed here
here we have energy density given as
so we have
so it is independent of the dimensions of the plate while total charge on the plates is constant always
so energy density will not change and remains the same
