Please explain why are S waves stopped by liquids.?

"S-waves" are shear waves, wheras "P-waves" are sort of push-waves (essentially).  So because fluids are umm... fluids, you can't shear them.  Shearing is when you deform something by applying unequal stresses from three dimensions.  With a fluid, such a stress would make no difference, because fluids cannot be deformed, they meerly move.  This is why an S-wave that hits a fluid will only be propigated as a P-wave!  Weee!

I don't fully understand what you are receffing to when you say waves. Do you mean brain waves?\n\nIn that case our feelings do influence our brain waves. I don't know much about this but hopefully someone on here can answer that.

Dear Little Giggl:  I think the answer to your question is VELOCITY, but it is NOT viscosity - which is the RESISTANCE property in liquid, that prevents quick flowing.\n\nFlow dynamics is said to be measured according to density and pressure which help determine velocity measurement of liquid.\n\nThank you for the question. . .it helped me to learn something.

Such a pulse produces a standing wave. In such standing wave energy is not transferred from one place to another.\n\nAt each instant we see a wave, but the waves do not move.\n\nThere are certain points which never move, they are called nodes.\n\nBut between nodes the points are displaced.\n\nAt one instant, all points are motion less.\n\nAfter this instant, points that previously went up will now come down and vice versa.\n\nExcept the nodal points, all points are oscillating between potential and kinetic energy. \n\nThe maximum displacement corresponds to potential energy and the mean position corresponds to kinetic energy.\n\nAt the instant when all points are motion less, ALL POINTS EXCEPT THE NODAL POINTS have kinetic energy, by which they continue their oscillation.

My guess would be that given your level of english comprehension you have never studied physics.  I suggest you watch "Star Trek" for starters and then move on to more advanced lessons like Terminator movies that show cyborgs that have liquid metal properties. \nNext look at a space shuttle and wonder how the hell they get that thing back to a runway 2 miles long from outer space.\n\nThe answer is PHYSICS.

The gas is under pressure, so when you press the nozzel the liquid ....mmmmmm better a picture than words..\n\n http://www.aerosol.com/

Water is not a good conductor of electric current it conducts electric current because of the impurities present in it.\n\nWhy?\n\nWith this simple experiment you can verify that the distilled water presents a very low conductivity because the potential of the first circuit is much less than the developed by the battery. The small potential of this circuit is due to the presence of the H+ and OH- ions produced when some molecules of water are dissociated. However, the number of molecules of water that are dissociated is practically negligible, making the distilled water a weak electrons conductor. It is worth noting, that as the distance among electrodes increases, the resistance to the electrons transfer in the distilled water increases considerably. This fact evidences even more the low conductivity of the distilled water.\n\nWhen salt is added (NaCl) to the system, the conductivity of the system increases considerably. The water not only dissolves the salt, as well as it dissociates the salt molecule. The elementary sodium (Na) presents an excess electron and the chloride (Cl) has a strong affinity for electrons. Consequently, after dissociation, the sodium loses an electron to the chloride, forming Cl- and Na+ ions. The presence of these ions increases the conductivity of the water considerably. The positive ions (Na+) migrate to the negative electrode (linked to the pole - of the battery) and the negatives (Cl-) migrate to the positive electrodes (linked to the pole + of the pile). The conductivity of the aqueous solution water/salt is proportional to the ions concentration in the solution.\nWhen you try to measure the conductivity of tap water you can verify that it has higher conductivity in comparison with distilled water because this contains ions (less pure). The tap water has higher conductivity due to the presence of the ions: Ca2+ and Mg2+. And don´t forget, try the science at home!

Because they started as gas/liquid, and round is the lowest energy state for a liquid.\n\nLike a raindrop.

i would think that the radiation from the freqs listed above should all cause excite the water molecules in the same way but to differing extents. that's a very good question; i think i'll research it.

IT SHOWS THAT THE EARTH HAS A fLUID CORE, BECAUSE S-WAVES DISSAPTE IN FLUIDS AND DO NOT PASS THROUGH, p-WAVES (STRAIGHTER THAN S WAVES) ARE ABLE TO PASS THROUGH FLUID. tHE WAVES THAT ARE REFRACTED OR PASS THROUGH THE FLUID (p-waves) ARE SAID TO APPEAR UP IN A SHADOW ZONE. Only p-waves show up in the shadow on the oppisite side of the core

water waves bounce back (reflected) when they travel in a medium and they meet an obstacle... if the obstacle has two opeings, they pass trough the openings but are bent (diffraction)... if your liquid is composed of two things like oil and water maybe, the speed of your waves will change (refraction) because waves are already passing through two diffferent mediums... the speed chanegs when waves pass through the inerface....

Seismic waves are basically waves of energy caused by the sudden breaking of rock within the earth or even a massive explosion such as a volcano. They are the energy that travels through the earth and this energy will then get recorded on seismographs.\n\nThe first kind of seismic waves are known P wave or primary waves. This is the fastest kind of seismic wave. The P wave can move through solid rock and fluids, like water or the liquid layers of the earth. It pushes and pulls the rock as it moves through just like sound waves push and pull the air. If  you have ever heard a  thunder and have also heard the windows rattle at the same time this is an example. The windows rattle because the sound waves were pushing and pulling on the window glass much like P waves push and pull on rock. Usually we only feel the bump and rattle of these waves.\n\nThe second type of seismic wave is the S wave or secondary wave, which is the second wave you feel in an earthquake. An S wave is slower than a P wave and can only move through solid rock. This wave moves rock up and down, or side-to-side.\n\nThese 2 types of waves are known a body waves, next come surface waves or L waves. L waves exist because of the Earth’s surface.  They are largest at the surface and decrease in amplitude with depth. L waves are known only to move along the surface of the earth. There speeds vary depending on the material, rock or soil, forming the surface. These waves cause the surface features such as buildings to move from side-to-side.

c basically boiling of a liquid means the vapour pressure[pressure created at surface] equals the atmospheric pressure.the increase in vapour pressure is due to the fact that the kinetic energy of molecules movin thermal velocities because of increase in temp. therefore for some molecules the time taken by molecules to achieve this situation is faster as the molecules have diff forces of attraction .hence to break the forces and achieve the above situ. is diff for diff. liquids \n\n\nhope this is satisfactory any more queries  mail me

dont ask us your homework online, you actually need to learn the stuff.\n\nappended:\n\nliquids are gasses, but something a gasses become liquids when they are pressurized enough to where gravity is able to overcome the kinetic (heat) energy of the mollicules.this causes  seperate from lighter gasses, and sink to the bottom. at low pressures or gravity, liquids become gasses, and vice versa.

This is a complicated question to answer completely, but there are some things one knows.\n\n1. S waves will not travel through fluids since they are tranaverse waves. If there is a part of the earth (like the outer core) that S waves will not travel through, then you know it is fluid. \n\n2. Different types of materials have different speeds of P and S waves\n\n3. Waves can get trapped at boundaries and get to the destination faster (head waves)\n\n4. Waves will bounce off boundaries between two different materials, and show up in the recordings. \n\n5. There are formulae giving speeds of P and S waves in terms of the continuum mechanical properties of the material. \n\n6. The phases, frequencies, and amplitudes, phase and group velocities, travel times, etc of the waves that travel through the earth are all data that can be used to infer the earth's structure. \n\nThere is a lot of analysis that is conducted on seismic data to produce pictures of the interior. The signals are carefully processed, and then turned into pictures of the interior. \n\nOf course, there is a lot more detail in all of this, but this should give you a general idea to start.\n\n----------------\n\n\nHere is a my answer to a previous question about this that might be helpful:\n\n  \n\n\n \n\nThe types of seismic waves, and their amplitudes and speeds, that are transmitted through a material depend on the properties of the material. \n\nFor example, transverse waves will not travel through liquids, only solids. So the transverse S waves produced by a seismic event will not pass through the fluid inner core of the earth. Different layers between different types of materials in the earth produce reflections, so looking at the reflected seismic waves can tell something about the structure and the boundaries between regions in the earth. \n\nMore sophisticated methods for imaging the earth's interior can also be constructed. Seismic simulations can be produced and the models that produced these simulations compared with the observed seismic signals. Using exhaustion or more sophisticated optimization techniques, scientists can refine these models of earth structure. More advanced inverse methods can be developed to infer features of earth structure. \n\nInstead of using high frequency seismic waves, one can look at a seismic modal decomposition, and then develop terrestrial models that reproduce the frequencies, amplitudes and phases of the observed free oscillations using inverse methods.\n\nThe actual details can be quite complicated, and many aspects remain open problems.\n\n-----------\n\nI have attached a link to the previous question and answers that are similar.

It's because p waves are faster than s waves, so the difference is related to how far away the source is.  The bigger the difference, the farther away.

Waves are the flow of energy through water.  There's quite a bit of energy in water and it can easily move as water is liquid, thus you observe a wave.  The water isn't actually moving much; each water molecule is moving just a bit and pushing the next molecule, which does the same and on it goes..
