Question

state and prove Bernoulli's theorem on the basis of the bernoulli's theorem explain why it is advised not to stand near a running train ​

Answer 1

Answer:

For the streamline flow of non-viscous and incompressible liquid, the sum of potential energy, kinetic energy and pressure energy is constant. Proof: ... This work done on liquid by pressure increases it's kinetic energy and potential energy.

When train moves with high speed it creates region of lower pressure and this low pressure push man towards the train. Hey! People are advised not to stand near fast moving train because: <> Due to its high speed it creates region of low pressure near it.
