Question

Just need answer, dont do number 12.

Longitudinal sound waves cannot propagate through solids steam wet sand liquids gases a vacuum X-ray diffraction can be used to measure what property of crystals? atomic spacing Rydberg constant atomic weight ionization potential density Earthquakes produce two kinds of seismic waves: he longitudinal primary waves (called P waves) and the transverses secondary waves (called S waves). Both S waves and P waves travel through Earth's crust and mantle, but at different speeds; the P waves are always faster than the S waves, but their exact speeds depend on depth and location. For the purpose of this exercise, we assume the P wave's speed to be 8500 m/s while the S waves travel at a slower speed of 5520 m/s. If a seismic station detects a P wave and then 34.5 s later detects an S wave , how far away is the earthquake center? Answer in units of km

Explanation / Answer

14) vacuum

15)density

9)y=Asin((2*pi/lambda)(x-vt))

v=f*lambda

v=383*2.5=957.5m/s

10)sound

8)lambda=v/f=3*10^8/103.1*10^6

=2.9m

1)shortest am wavelength =187.37 metres

2) Longest am wavelength = 545.076 metres

3)shortest fm wavelength=3.41m

4) longest fm wavelength=2.77m

5)0.395 Hz

6) 0.205m

7).0.763HZ
