How many seismometers do you need at a given place to fully record the motions arising from earthquake waves?
You need a seismometer for each axis of motion. As such it takes three seismometers.
How many types of surface waves are there?
The three basic waveforms are Sine, Triangle and Square waves. For transmitting, the only one that matters is the Sine wave because it has no harmonics of its own. A "harmonic" is an unwanted emanation running at an exact multiple of the frequency you're trying to use.
Describe how energy released at an earthquake's focus can cause damage on the surface many kilometers from the epicenter?
The movement of seismic waves
What are P S and L waves?
They are seismic waves - those emitted by an earthquake. P-waves are known as primary waves. They have the fastest velocity of all the seismic waves and so arrive at a seismometer station first. They are a longitudinal or compression wave. S-waves are secondary waves. They travel more slowly than P-waves, but faster than surface waves so are the second seismic wave to be recorded at a seismometer station. They are transverse or shear waves. Finally there are the surface waves of which there are two main types. The L-wave or Love Wave and the R-wave or Rayleigh wave. These waves tend to have the largest magnitude and cause the majority of the damage that occurs during an earthquake.
How does seismic waves reveal the structure of Earth?
Seismic waves have helped scientists learn the various densities of the Earth's many layers because the speed of primary shock waves moving through the earth generally increases with depth. This is because as density increases, seismic wave velocity increases. While P-waves travel through the Earth's crust at an average of about four miles (6.4 km) per second, they reach an average of seven miles (11.3 km) per second at the center of the Earth. When the shock waves suddenly shift in direction and speed, scientists are able to determine the depths at which Earth's various layers are located. Three different types of waves travel away from the focus of a seismic event. These waves travel at different speeds. In addition to surface waves, the waves that are proving critical to providing evidence about the interior of the Earth are 'P' waves (P standing for primary or pressure), and 'S' waves (S for secondary or shear). P-waves are faster than S-waves. P-waves can travel through solid rock and fluids, and their speed will vary depending on the density of the rock through which they travel; increased speed will indicate increased density, thus providing information about the density and possible mineralogy of Earth's various layers. S-waves cannot travel through fluids, thus when an S-wave encounters the outer core of the Earth (liquid iron and nickel), it is disrupted, indicating the boundary between the mantle and outer core and the boundary between the inner core and outer core. The effect observed from the motion of S-waves reveals a 'shadow zone', opposite to where they originate.
How many bones are in just the human hand?

How much fps does a 44 magnum have?
How many feet per scond? depends on the laoding of the cartridge, and what it is fired from. For most handguns, between 1300 and 1600 feet per second.
When the frequency and wavelength are known answerer?
Frequency refers to how many waves pass a fixed point in a unit of time. Frequency is measured in Hertz, or Hz, and one Hertz means a single wave passes a given fixed point in one second. Wavelength refers to the length of an entire wave, so either from crest to crest or trough to trough. If you know how many waves pass a given point in a unit of time, which is frequency, and how long the waves are, which is wavelength, you can find the wave's speed. For example, if a wave has a frequency of 10 Hz, so ten waves pass a given point in a second, and it has a wavelength of four meters, you multiply the frequency by the wavelength to find that the waves are traveling at 40 meters per second.
Particles or waves given off by atoms undergoing nuclear decay produce?
Produce a large amount of heat and energy which is utilized for many purposes
How can you measure the surface temperature of the sun?
Indirectly, by analyzing the light given off by the Sun. Typically, a hotter object will emit electromagnetic waves of higher-energy - on average, because such an object will emit a mix of many electromagnetic waves.
How many pages does The Waves have?
The Waves has 324 pages.
How many seismometers do you need at a given place to fully record the motions arising from earthquake waves?
You need a seismometer for each axis of motion. As such it takes three seismometers.
How many waves are produced in one second?
It depends (IS) the frequency of the waves.
How many pages does The Sound of Waves have?
The Sound of Waves has 182 pages.
How many waves are there in gears of war 2 horde?
50 waves
How many waves is there on mw3 survive?
There are unlimited waves on survival mode.
Is it true waves given off by electric power lines are too long to be seen?
Yes. What you need to look at is the electromagnetic spectrum. There are many great graphical illustrations of this on the web.
