Why we do not crush under air?
Equal pressure inside us.
Why does the pressure decreases when you are in a high mountain or in the peak of the mountain?
Air pressure is the weight of the air above you. When you ascend to some altitude above the Earth's surface, part of the air is beneath you, so the weight of the air above you, and therefor the pressure where you are, is reduced. Exactly the same reason that the pressure on the football player in the middle of the pile-up is less than the pressure on the guy with the ball, at the bottom of the pile.
What are two ways that friction can be useful?
These came of of the top of my head so here it is it can be used to produce heat or to slow things down in the air. Hope this helped:)
What is the relationship between air pressure and flight?
Air exerts pressure in the same way that water exerts pressure on a diver. Air has weight, and because we are at the bottom of a blanket of air that surrounds the earth, the weight of that air is pressing down on us (creating pressure). If you go under water, you'll feel the additional pressure created by the weight of the water above you.
How does a face mask help us breathe clearer air?
If you all look closely at the back of the face mask, you can see some tiny holes. When you breathe in the air, the hole will act like the hair in your nose and trap the dust. That will prevent dust from entering your body. That is how face masks help us to breathe cleaner air.
What happens when the air molecules that are constantly pressing down on us due to gravity?
it squeeses use a bit if it is alot it will crush use
Why is the force exerted on the same amount of area on top of the mountain less than the force exerted at sea level?
Although you didn't mention air pressure, that seems to be what you are asking about. Air exerts pressure because air has weight, and we have a very thick atmosphere (which extends upward for about 200 miles) pressing down on us. But at higher altitudes, such as a mountain top, there is less air pressing down, since only the part of the atmosphere that is higher than where you are, is pressing down on you.
Why does air pressure becomes lower as water molecules are added to the air?
Air pressure is the weight of the air at a specific location. On the surface of the earth, we have the entire weight of the atmosphere pressing on us in the form of air molecules like O2, N2, and CO2. As we go higher and higher into the atmosphere, there are fewer molecules and so there is less weight pressing against us.
Why does air in the atmosphere pressure down on us?
It is the pull of gravity on the column of air over you.
What was the US accomplishments on DDay?
They landed on Normandy beach.. and were pressing inwards into Europe to take down the Nazi regime
What is the best explanation for how air masses move across the US?
the air goes up and down
Is the US still pressing pennies?
Yes.
What is the name of Utahs US Air force base?
Hill air force base.
When was the name US Army Air Corps discontinued?
President Truman brought the US Air Force into existence in 1947. The Korean War was the FIRST war fought by the US Air Force.
What is the force of air pushing down on us?
14.7 psi (at sea level).
What is the name of the force that pulls us down?
gravity
What was the name of the American Base in Turkey?
Incirlik Air Base was the name of the US Air Force base, but it was renamed the Adana Air Base on February 21, 1955
