Why does the pressure under a train need to be low?
On the typical train, there is no effort to control pressure above or below a train.
What force is created by high pressure under a wing and low pressure above a wing?
Lift
What type of air pressure creates a tornado?
Tornadoes form under conditions of low pressure
Why are sleepers laid down under the rails of the trains?
this is because sleepers increase the area on which pressure of train is to be exerted.Thus pressure is not concentrated on a single point densely.therefore if there more area there would be less pressure and train will run smoothly
Why it is dangerous to stand near a railway line when a fast train is passing by?
Probably for the same reason you don't want to hang out next to a sinking ship or stand under a passing airplane - the air or water nearby is being pushed aside and creating a vortex. The air disturbance along with the ground vibrations may cause you to lose your balance and possibly fall into the passing train and maybe die. When a train is moving at a high speed; the velocity of air increases; according to bernoulli' s theorem, as the velocity increases, the pressure decreases. Thus the place where we are standing is a region of high pressure and the place where the train is moving is a region of low pressure. We are pulled from a region of high to a region of low pressure.

What are the three things that help keep the pressure low under a train?
There is nothing that is specifically designed to keep the air pressure low under a train. A train is kept on the tracks by gravity, nothing more.
How do you keep the pressure under a train low?
because if not then you have friction and friction causes massive problems

Is the outer core is under low pressure?
no, it is under extreme pressure
Which solution will have more gas dissolved in it a solution under high pressure or 1 under low pressure?
A solution under high pressure will have more gas dissolved in it than one under low pressure.
Is earth's outer core under low pressure?
no it is under high pressure
Which solution will have more gas dissolved in it solution under high pressure or one under low pressure?
the solution with higher pressure would have more gas in it that the one with low pressure.
Which solution will have more gas dissolved in it a solution under high-pressure or under low pressure?
A solution under a high pressure
Earthes outer core us under low pressure?
It is under lower pressure, however, it is under pressure enough to compress it into a liquid.
Under which conditions does a real gas behave most like an ideal gas?
During low pressure, and low temperature conditions
Which solution will have more gas dissolved in it a solution under high pressure or under low pressure?
A solution under a high pressure
