Answer:

Is the source an authority on the subject?

Explanation:

To figure out which source is accurate, you want to find out the source's authority on the subject. For  example, if you wanted to learn how to play the piano, you wouldn't go to a dance teacher, you would go to someone who knows how to play the piano. The person who knows how to play the piano has more authority to teach the piano than a dance teacher.

Yanka [14]

Answer:

its 0.163 g

Explanation:

From the total pressure and the vapour pressure of water we can calculate the partial pressure of O2​

PO 2 =P t −P H 2 O

​= 760 − 22.4

=  737.6 mmHg

From the ideal gas equation we write.

W= RT/PVM = (0.0821Latm/Kmol)(273+24)K(0.974atm)(0.128L)(32.0g/mol/) =0.163g

A. They are the most destructive earthquake waves.

D. They can move in a rolling pattern through rock, like an ocean  wave.

Explanation:

Surface waves are seismic waves that cause the most destruction during an earthquake.

Rayleigh waves are known to cause rolling pattern of rocks just like an ocean waves.

  • Seismic waves are elastic waves that notably transmits energy.
  • They usually accompany earthquakes.
  • There are two broad categories of these waves.
  • Surface and body waves.
  • Seismic surface waves are low frequency and long wavelength waves.
  • They travel very close to the surface.
  • They are made up of Love and Rayleigh waves.
  • Love waves travels laterally in a horizontal fashion.
  • Rayleigh waves rolls like ocean waves in the ground.
  • The bulk of the destruction caused during an earthquakes is due to these waves.
  • They are the last waves to arrive a seismic station
