A partially inflated balloon is released from the ground level and becomes larger as it rises in the atmosphere?
It is true that it will become larger as it risses in the atmosphere. This is because the pressure surrounding the balloon decreases, so the pressure inside the balloon wants to equalise with the outside pressure. This causes the balloon to expand as the inside air is trying to get out. That's why things get 'sucked out' of a plane if there if someone opens the door at 30,000 feet, the cabin pressure is trying to equalise by removing the objects and air inside it.
When an aeroplane flies its doors and windows are completely sealed.why we are not allowed to open windows even slightly?
A modern high flying aircraft has a pressurised cabin, so that the passengers can breath normally. If a window was to suddenly break, the air pressure inside would rush out of the broken window as the air pressure in the atmosphere outside to plane is very much less. If this was to happen, oxygen masks automatically fall from the ceiling so the passengers will be able to breathe. Otherwise, the pilot would be forced to descend rapidly to a lower altitude before the passengers blacked out due to lack of air.
Can a simple inclined plane have a mechanical advantage less than one?
The mechanical advantage of an inclined plane is the ratio of its length to the height of its lift. At 45 degrees, this ratio is equal to one. Less than 45 degrees and it is greater than one, more than 45 degrees, and it it less than one. So the answer is yes.
What is the control in the paper plane experiment?
what can be the constant in the paper plane experiment
Inclined plane is step ladder and?
Ramps are another example of inclined plane.
Why can't you open a window on a plane?
The pressure is much less outside the plane and opening the window would cause a rapid movement from high pressure inside to low pressure outside and suck things out of the plane window.
Why do you have to open windows on a plane when landing?
Opening windows on a plane during landing helps equalize the pressure inside and outside the aircraft, which is important for safety and comfort.
Why ink spil out from pen in the aero plane?
Because as altitude increases, air pressure decreases. As the plane rises, the air pressure inside the pen is higher than outside it causing the ink to spill out.
What Happens if a Plane Goes Higher Than it's Designed To?
As the air pressure outside the aircraft decreases, & the air pressure inside the aircraft remains the same, it remains very high inside the aircraft in comparison to the outside, so in the end, the fuselage will explode apart, because the air pressure outside is not enough to counter act it & push against the force of the air pressure inside the aircraft which is pushing outwards.
Why do animals' ears pop on planes?
When animals are on a plane, the change in air pressure can cause their ears to pop. This happens because the pressure inside their ears needs to equalize with the pressure outside, which can be uncomfortable for them.
Why do your ears hurt during take off and landing?
The pressure outside of your eardrum in the plane changes as the plane goes up or comes down - this causes pain because the pressure behind your eardrum is either higher or lower than the pressure inside the plane.
Sweets are given to the passangers before the plane takes off the ground?
Basically, when the plane takes off, you gain altitude very quickly. This gain in altitude causes a decrease in pressure because the weight of the atmosphere above you decreases. The inner ear is highly sensitive to pressure changes and when the pressure around you drops, the pressure being exerted from the inside of your ears will be greater than that around you causing your ear drums to 'pop'. The action of swallowing and sucking on the sweet will constantly force your ear drums open so that you will constantly equalize the pressure inside and outside your ear.
Why are air plane cabins pressurized?
Outside the plane is way less pressure and less air to breath. If inside the plane was the same pressure as the outside, people might die depending on how high the plane is. ***************************************************************************** FAA law mandates an un-pressurized aircraft the pilot and co-pilot must wear oxygen masks at or above 12,000 feet ASL altitude. Hypoxia sets in with no warning and no symptoms.
Why is it necessary for windows to be open during takeoff?
It is necessary for windows to be open during takeoff to equalize the air pressure inside and outside the aircraft, which helps maintain the structural integrity of the plane.
In a very fast moving car or plane why air is going out?
In a fast moving car or plane, the air inside experiences increased pressure due to the vehicle's motion. As a result, the air is pushed out through openings like vents or windows to equalize the pressure inside and outside the vehicle. This is similar to how wind is generated by the movement of air masses at different pressures in the atmosphere.
Why are you advised to empty ink from your fountain pen before boarding an airplane?
Although a plane is pressurized it is not pressurized completely to ground or takeoff level. As the plane climbs the air pressure in the cabin is decreased with higher altitude. A typical airliner has the equivalent cabin altitude of 5,000 to 8,000 during cruise. The difference in pressure between the cabin air and that inside the ink cartridge of the pen draws out the ink as the pressure inside the pen is more than that outside.
Why do potato chip bags expand while flying on an airplane?
As you get further from sea level, the air gets thinner; when you fly in a plane they keep the air inside thicker than the air outside so you can breathe easily, but it's still thinner than on the ground. A chip bag is sealed on the ground, so when it gets up to where the air is thin the pressure inside is still the same as it was down near sea level; that means the chip bag swells as pressure inside stays the same but pressure outside drops.
