Answer:
<em>Barometers measure this pressure. ... Changes in the atmosphere, including changes in air pressure, affect the weather. Meteorologists use barometers to predict short-term changes in the weather. A rapid drop in atmospheric pressure means that a low-pressure system is arriving.</em>

Lol i need to answer more and plus n could also = # 4.65
I know the answer but i really don’t
<span>Answer:
I'm assuming the question is asking when it "jumps" from level 2 to level 1. In which case: 1/λ = Rh(1/nf^2 - 1/nfi^2) = 1.10x10^7 (1/1^2 - 1/2^2) = 1.10x10^7 ( 1 - 0.25) = 1.10 x10^7 (0.75) λ = 1.21 x 10^-7 m The wavelength produced will be about 1.21 x 10^ -7 m, or 121 nm.</span>
Answer:
Explanation:
Total pressure = partial pressure of nitrogen + partial pressure of water vapour
partial pressure of water vapour = 18.7 mm of Hg
760 mm of Hg = 1 atm
18.7 mm of Hg = 18.7 / 760 atm
= .0246 atm
Total pressure = partial pressure of nitrogen + partial pressure of water vapour
Putting in the values in atm
1.72 atm = partial pressure of nitrogen + .0246 atm
partial pressure of nitrogen = 1.72 atm - .0246 atm
= 1.6954 atm
= 1.70 atm
partial pressure of nitrogen = 1.70 atm .
