Compare S (secondary) waves and P (primary) waves. Why do they travel at different speeds?

Chemistry

Amanda [17]3 years ago

S waves

  • These are shear waves .
  • The motion of the medium is perpendicular to  direction of propagation of the wave .
  • They can propagate only through solids and not through gases or liquids .
  • S waves are larger .
  • They travel with less speed .

P waves

  • These are compression waves .
  • These waves produces a force along the direction of propagation .
  • They can propagate through solids, gases and liquids.
  • P waves are smaller than s waves .
  • They travel with 60% greater speed than S waves .

P-waves travel 60% faster than S-waves on average because the interior part of the Earth does not react the same way as the s wave and P wave.

Verizon [17]
The answer is iii) decreasing the pressure of the system. When the pressure is decreased, the equilibrium will shift to the right because it has 12 moles of gas which is greater than the number of moles of gas on the left side, which is 6 moles. Equilibrium shifting to the side that exerts greater pressure is favored to offset the decrease in pressure.

If the acceleration is 600 m/s/s and the mass is 300 kg, what force is acting on the object?
vampirchik [111]

Explanation:

Acceleration (a) = 600 m/s²

Mass (m) = 300 kg

Force (F) = ?

We know

F = m * a

= 300 * 600

=180000 Newton

The force acting on the object is 18000 Newton.

1(a). What is the solubility of calcium chloride (CaCl2) at 5°C?
In-s [12.5K]

Answer:

60 g/100 g water  

Explanation:

Find 5 °C on the horizontal axis.

Draw a line vertically from that point until you reach the solubility curve for CaCl₂.  

Then draw a horizontal line from there to the vertical axis.

The solubility of CaCl₂ is 60 g/100 g water.
