Why does the pressure under a train need to be low?
A low pressure under a train helps to minimize the drag force caused by air resistance, allowing the train to move more efficiently. It also reduces the risk of creating a partial vacuum underneath the train, which could impact its stability.
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.
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.
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.
Which solution will have more gas dissolved in it a solution under high-pressure or under low pressure?
A solution under a 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.
Earthes outer core us under low pressure?
It is under lower pressure, however, it is under pressure enough to compress it into a liquid.
Which solution will have more gas dissolved in it a solution under high pressure or under low pressure?
A solution under a high pressure
How does a basketball under high pressure compared to a basketball under low pressure?
There are more particles of gas.
Does a solution under high pressure or low pressure have more gas in it?
A solution under high pressure will have more gas dissolved in it compared to a solution under low pressure. This is because the higher pressure forces more gas molecules to dissolve into the solution.
