Why is pressure low under a train?
Pressure underneath a moving train is lower because of the Bernoulli's principle, which states that as fluid (such as air) moves faster, its pressure decreases. The train's movement creates airflow beneath it, causing the pressure to drop.
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.
Why does a piece of paper bend as you blow under?
When you blow under a piece of paper, the air flow creates a low-pressure area under the paper, causing it to bend towards the side with higher pressure (usually the top side). The pressure difference between the top and bottom of the paper results in a lifting force that causes the paper to bend.
Does a cyclone have high pressure?
No, a cyclone is associated with low pressure at its center. Air converges at the center of a cyclone, causing the air to rise and creating a region of low pressure.
Is the center of a tornado characterized by low or high pressure?
The center of a tornado, known as the eye, typically has low pressure. As air converges towards the center, it rises and cools, resulting in the creation of a low-pressure area.
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 pressure low under a train?
because if not then you have friction and friction causes massive problems

What explodes under low pressure?
Anything expandable/flexible will expand under low pressure. but in order for it to explode I guess you need to contain it within a relatively thin container made of stronger material. eg. balloon
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.
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.
What effect does a fast moving train have on a man standing near it?
the man falls towards the train because the stream lines of air near train are closer greating more pressure where as stream lines naer man are farther creating low presssure thus the man moves from the area of low pressure to that of high 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
