Is a black hole an example of negative pressure?
No. The only force at work with a black hole is gravity.
What uses air pressure to work?
air
Explain how negative work on a system occurs?
The system is doing net work.
What is the sign of the work done by the frictional force?
Negative
What were the negative effects of Louis Pasteurs work?
mabey
How do chest tubes work to fix a collapsed lung?
I am not in the medical field. But if a lung collapses it means that there is air getting between the lung and the chest cavity creating pressure against the lung. A tube placed in the chest wall will relieve the pressure there. When the lung fills with air it pushes the air out of the tube. Then you can block the tube to give the chest cavity back the slight vacuum it had before. That is why your chest expands when you breate in. I hope this is right and I am not stepping on any toes out there.
Why our ears pop when we ride in an airplane or when we drive to the mountains?
There is a little tube connecting the back of our nose with the middle ear cavity. This little tube (called the Eustachian tube) regulates air pressure in the middle ear to equal the changing outside air pressure.The Eustachian tube normally rests closed but opens about 400 times per day to quickly regulate pressure differences (think of a water bottle indented until the cap is removed and "pop" the pressure is equalized).When we drive through the mountains or fly in an airplane or scuba dive, the pressure changes. The little tube opens (the "pop") and relieves the build up of negative pressure in the middle ear.When we feel pressure building, we often will yawn, swallow, or do the Valsalva Maneuver to get our "ears to pop". When these things don't work, negative pressure builds and fluid can be pulled in from the surrounding tissue.Ear pain, pressure, and hearing loss can result. Instant relief can be experienced when the Eustachian tube opens and relieves that built up pressure.Hope that helps! It's really all about the little Eustachian tube doing its job!
If a process is carried out at constant pressure P and the volume V of the system decreases then V is negative positive and the work w is negative positive zero?
In this case, V would be negative, and work w would be positive.
How does a hydraulic gauge work?
Normally using a calibrated bellows or bourdon tube. As pressure is sensed by the device it inflates the tube or bellow which in turn causes the needle to rotate. Pre-seventies pitot and static systems on aircraft use this very technology to relay information like true air speed to the pilots.
Is a black hole an example of negative pressure?
No. The only force at work with a black hole is gravity.
How does the thermometor work in a mirror?
Thermometer usually works with a lead pressure tube. Latest sensors have taken its place.
How does a hydraulic lift work?
A hydraulic lift works by having pressure travel through a tube into another. One tube is smaller forcing air into the larger one in order to push and raise the lift.
Does working out your abs lower your chest?
No,it does not lower chest when you work out your abs....
Can work done by a force be negative?
Yes. If force is negative, then work will be negative.
What jobs do they work with the muscular system work with?
chest
When work is positive and when is negative?
when work is positive and when playing is negative
Where is the Orifice Tube on a 1999 Ford Escort?
It is on the left (drivers) side of the engine compartment near the headlight. It is in the line that runs from the condenser mounted on the radiator, to the evaporator in the passenger compartment. MAKE SURE THERE IS NO PRESSURE IN THE SYSTEM BEFORE YOU WORK ON THIS PROJECT. There is a valve right next to the orafice tube so that you can ensure there is no pressure on the high side.
