The doppler effect.
You are welcome.
Make a proportion
3 H2 - 2 NH3
19H2 - x
x = (19x2)/3= 12,666666
Position: x = 18t y = 4t - 4.9t²
First derivative: x' = 18 y' = 4 - 9.8t
Second derivative: x'' = 0 y'' = - 9.8
Position vector: P = (18t) i + (4t - 4.9t²) j
Velocity vector: V = (18) i + (4 - 9.8t) j
Acceleration vector A = (- 9.8) j
C. Mechanical, because temperature can cause solid objects to expand and contract, causing rocks to split apart.
Answer:
Condensation.
Explanation:
The boiling point of water is much higher than that of either nitrogen or oxygen gas . So when the mixture is condensed to a temperature lower than
100°C , water vapor will come out first in the form of water leaving other
elements of mixture in gaseous phase. In this way, water vapor will get separated from others.
