Nevado ojos Del salados is a stratovolcano in the Andes on the Argentina Chile border and the highest acetic volcano In the world at 6,873m (22,549ft.)
Answer:
<em>The 1/2 inch barrel will burst at the same height of 20 ft</em>
Explanation:
The pressure on a column of fluid increases with depth, and decreases with height. This means that if you increase the height of the fluid in the column, the pressure at the bottom will increase.
From the equation of fluid pressure,
P = ρgh
where
P is the pressure at the bottom of the fluid due to its height
ρ is the density of the fluid in question
h is the height to which the water stand.
You notice how apart from the height 'h' in the equation, all the other parts of the right hand side of the equation cannot be varied; they are a fixed property of the fluid and gravity. And there is no consideration for the horizontal diameter of the water's cross section area.
We can also think of the pressure at the bottom of the fluid to be as a result of an incremental weight of an infinitesimally small vertical section of the water down.
That been said, we can then say that if the barrel with the 1 ft diameter dimension bursts when filled with water up to 20 ft, then, the barrel with the reduced diameter will still burst at the same height as the former pipe.
NB: The only way to stop the pipe from bursting is to increase the thickness of the barrel wall to counteract the pressure forces due to the height.
Answer:
The boiling point of liquids always increases when pressure is applied on a liquid. This is because the molecules of a liquid will need more energy to turn into a gaseous state when pressure is applied on that substance.
Electrons will always take the path with the lower resistance. For example, think of it like driving. If there are more things to slow you down on Road A, such as a traffic jam, you'd want to take a Road B because it has less things to slow you down. Electrons want to do the same thing. Essentially, they want to go into the path which is 'less clogged up', and over time, electrons will clog up with paths with higher resistance. it's called resistance for a reason, it "resists" electrons/current! Hope this example helped clear things up!
