Which of the following affects the speed of a seismic wave?
scoray [572]

Explanation:

The speed of seismic waves is affected by the density of the underlying rock.

Seismic waves are elastic waves that transmits elastic energy from one point to the other.

These waves generally produced during an earthquake.

  • The higher the density of rock bodies, the faster the wave travels.
  • Rocks that are well packed with little to no void have a higher seismic velocity.
  • Where density of rock is low, the speed is also low

A sealed helium balloon with an internal pressure of 1.00 atm and a volume of 4.50 L at 293 K is moved. What volume will the bal
bixtya [17]

Answer:

6.48 L

Explanation:

From the question,

Applying

PV/T = P'V'/T'......................... Equation 1

P = initial pressure of the helium balloon, V =  Initial volume of the balloon, T = Initial temperature of the balloon, P' = Final pressure of the balloon, T' = Final temperature of the balloon, V' = Final volume of the balloon.

make V' the subject of the equation

V' = PVT'/P'T......................... Equation 2

Given: P = 1 atm, V = 4.5 L, T' = 253 K, T= 293 K, P' = 0.6 atm

Substitute these values into equation 2

V' = (4.5×1×253)/(0.6×293)

V' = 1138.5/175.8

V' = 6.48 L

Which of the following expressions is the correct equilibrium-constant expression for the equilibrium between dinitrogen tetroxi
nekit [7.7K]

Answer:

D. [NO₂]²/[N₂O₄]

Explanation:

The equilibrium constant expression for a reaction is products over reactants. Since NO₂ has a coefficient of 2, it will become an exponent.

So, it would be:

[NO₂]²/[N₂O₄]

Hope that helps.
