Answer:
Explanation:
given reaction
2O₃ ⇄ 3O₂
initial 1 1
final 1-x 1+ 1.5x
rate of reaction = k [ O₃ ]² / [ O₂ ]
initial rate = k . 1² / 1 = k
final rate = k (1-x )² / (1+ 1.5x) = k/2
(1-x )² / (1+ 1.5x) = 1/2
2x² - 5.5 x + 1 = 0
x = 0.196
So fraction of ozone reacted = .196
Answer : The correct option is, transverse wave.
Explanation :
Longitudinal waves : It is defined as the waves in which the particles of the medium move in the direction of the wave.
Transverse wave : It is defined as the waves in which the particles of the medium travel perpendicularly to the direction of the wave.
Surface wave : It is defined as a combination of transverse and longitudinal waves.
From the given image we conclude that, this illustration depict the transverse wave because the particles of the medium move perpendicularly to the direction of the wave.
Hence, the type of wave is, transverse wave
Answer:
D
Explanation:
Universe consits of galaxies, galaxies consit of solar systems, and solar systems consist of planets
Efficiency of the ram is calculated by dividing the work done by the work or energy that is exerted to do so. This is calculated through the equation,
S = ((Wout) / (Win)) x 100%
Substiuting the known values to the equation.
S = (153 J)/(185 J) x 100%
Efficiency = 82.7%.
