What is the force of atmospheric of a blimp?
presses on all sides
What causes the pressure of the atmosphere?
Atmospheric pressure is caused by the force of the air above the earths surface. It is measured by the point in which the air meets the atmosphere.
Atmospheric pressure is caused by what?
force = pressure x area , so pressure is force divided by area, air molecules stack up on top of each other and the force of them (caused by gravity and their mass ) weighs down with a pressure of 14.7 lbs/sq inch or 1 bar. As you go higher the stack is lower so the pressure drops until you get to space and it measures a vacuum.
When Inside a star the force of gravity is balanced by the?
It is balanced by radiation pressure, and gas pressure.
How does the solar energy affect oceans and atmosphere movement?
Solar energy is the driving force of weather on Earth. In the "water cycle", the sun is responsible for evaporation of ocean surface water. As this happens, the water vapor rises. The combination of the Earth's rotation and the changes in atmospheric pressure is the primary determinant for when and where the rain comes down.
What best describes the force of atmospheric pressure on a blimp?
An air compressor blowing gasses into the blimp is what causes the air pressure in the blimp. These gases are lighter than air.
What is the force of atmospheric of a blimp?
presses on all sides
The force exerted by the weight of a column of air on a surface is called?
Air Pressure The force exerted by the air above is called?
What is the driving force for inspiration?
Atmospheric Pressure
Where does the force of a cyclone come from?
Cyclone is caused due to the variation of atmospheric pressure in the air. Especially in the low atmospheric zone, air comes from all sides to balance the atmospheric pressure in that area. That's why cyclone is created. So the force for cyclone comes from variation in atmospheric pressure.
Does atmospheric pressure still exert a force on you when you are under water?
Atmospheric pressure exerts more force on you if you are deeper than 10 meters. At 10m below sea level the atmospheric pressure is double that of on land and it increase with every 10 metres that you descend
Atmospheric pressure is a consequence of what?
The gravitational force on the Earth's air.
Why are you crushed by atmospheric pressure?
The force is equal to when you experience these feelings.
Why does the height of the column in a barometer changes as atmospheric pressure changes?
As the atmospheric pressure changes, the force pushing on the surface of the liquid changes. Therefore,the height of the liquid in the tube increases as the atmospheric pressure increases.
What factor is most responsible for Earth's atmospheric pressure?
gravity,friction,atmospheric condition,coriolis force
What is a force that results from a coloumn of air pushing down?
atmospheric pressure
Is it true or false the force that drives air into the lungs come from air pressure?
No atmospheric pressure
