What is the squiggle line called on the y axis of a graph?
When you are changing a scale on a graphic, you warn the viewer by using a squiggle line on the changed axis. If the bar is unusually long, the bar length is compressed with a squiggle in the bar itself.
Why can't a swimmer snorkel more than a meter deep?
"Because the pressure will cause the heart to explode." Well, no (the heart cannot "explode" anyways, rupture yes, but I'll leave it at that for now). The main problem is the pressure differential on the surface compaired to the lungs which are submerged. At one meter's depth the water adds 0,1 bar of pressure to the atmospheres 1 bar. This means that the lungs which are compressed to 1,1 bar (1 bar ATM and 0,1 bar of water) must overcome the pressure, making breathing impossible since the air cannot be drawn into the lungs.
Why is a rigid bar that rests on a fixed point called a fulcrum?
The rigid bar is not called a fulcrum! And, by the same token, why is the bar called a bar?
How are pie and bar charts the same and different?
pie charts show the percentage of whatever the chart is displaying and bar charts show the improvement or difference in what the chart is showing. they are the same because if both the pie chart and bar chart are being used for the same situation, the data should be the same.
What does a roman numeral with a bar above it?
The bar over the letters tells you to mulitiply it by 1,000.
Compressed air system for bus bar?
To avoid accumulation of moisture.
Do scuba divers breath pure oxygen?
Believe it or not, we can die from too little oxygen AND too much oxygen. This concept involves partial pressures. If we first consider using standard air (i.e. 20% Oxygen and 80% Nitrogen): (1 bar = 1 kilogram of pressure per square centimetre) At the surface - Total Pressure of air = 1 bar - Pressure of Oxygen = 0.2 bar - Pressure of Nitrogen = 0.8 bar At 10m - Total Pressure of air = 2 bar - Pressure of Oxygen = 0.4 bar - Pressure of Nitrogen = 1.6 bar At 20m - Total Pressure of air = 3 bar - Pressure of Oxygen = 0.6 bar - Pressure of Nitrogen = 2.4 bar At 30m - Total Pressure of air = 4 bar - Pressure of Oxygen = 0.8 bar - Pressure of Nitrogen = 3.2 bar At 40m - Total Pressure of air = 5 bar - Pressure of Oxygen = 1.0 bar - Pressure of Nitrogen = 4.0 bar At 50m - Total Pressure of air = 6 bar - Pressure of Oxygen = 1.2 bar - Pressure of Nitrogen = 4.8 bar At 60m - Total Pressure of air = 7 bar - Pressure of Oxygen = 1.4 bar - Pressure of Nitrogen = 5.6 bar At 70m - Total Pressure of air = 8 bar - Pressure of Oxygen = 1.6 bar - Pressure of Nitrogen = 6.4 bar It is at the partial pressure of 1.6 bar (which occurs at 70m where oxygen becomes toxic. That is why most dive organisations recommend 50m as a maximum for recreational diving. However, if pure oxygen is used: At surface - Pressure of Oxygen = 1 bar At 10m - Pressure of oxygen = 2 bar The oxygen has already become toxic! Hope that answers your question. The concept is called "partial pressures" and "oxygen toxicity" if you want to research more on a search engine.
How deep can a scuba diver go on compressed air?
If the gas is normal air (~20-22% oxygen), the maximum recommended depth of most dive organisations is in the region of 50-60m. The reason for this is that the deeper you go, the higher the pressure of the water. For example, on the surface, the pressure is 1 bar, 10m is 2 bar, 20m is 3 bar 30m is 4 bar etc. Oxygen becomes toxic to the human body at about 1.6 bar so if you are at 70m, with a mix of 20% oxygen, you are at 8 bar of pressure. At 8 bar, the parital pressure of oxygen is 1.6 bar, enough to become toxic. So compressed air becomes dangerous at 70m so most organisations advise to go no deeper than 50-60m. If you use a different gas blend, such as Nitrox ar Trimix, the amount of oxygen is different so the depths are different too. In summary, on compressed air, the maximum is about 70m, recommended 50-60m max.
What does nitrogen have to do with diving?
when you go diving, you take a pressurized tank of air, air consists of about 79% Nitrogen and 21% Oxygen, at normal pressure (atmospheric pressuer) the partial pressure of Nitrogen is 0.79 Bar and Oxygen 0.21 Bar which is safe. Under high pressures (say 5 Bar which is at a depth of about 40 metres) the partial pressure of each gas increases Nitrogen (0.79x5=3.95Bar) which causes the lungs to absorb the nitrogen at a higher rate which influences the nervous system causing Narcosis (As if you're Drunk) The reason why you can't take a tank of oxygen instead of air is that oxygen becomes toxic at higher partial pressures
Is the Wilson's Bacon Bar still made and sold?
No longer made but there is a Costco product that is just as good although not compressed into bar form.
When was Bar XH Air created?
Bar XH Air was created in 1974.

What is the Physical quantity measured in bar?
Pressure is the physical quantity measured in bar.
How do you make nitrogen?
The atmosphere of our planet is composed mostly of nitrogen, therefore nitrogen is readily available and doesn't have to be made. This is a bit like asking "how do you make water?" It's possible to make water - most forms of combustion produce at least some water vapor as a by-produc t - but it is never necessary to do so. It's much easier to use the water that we already have. But then, suppose you need pure nitrogen, 100% nitrogen, not air. Nitrogen can be separated out from air by a process of fractional distillation. Liquify the air (at very low temperatures) and the various components can be boiled off at different temperatures.
What is the squiggle line called on the y axis of a graph?
When you are changing a scale on a graphic, you warn the viewer by using a squiggle line on the changed axis. If the bar is unusually long, the bar length is compressed with a squiggle in the bar itself.
Is the menu bar always the same in excel?
Of course, for the same function, the bar will be the same. But for a different function, nope.
What is a bar patron?
A bar patron is a person that drinks at the same bar frequently.
