When a straw with liquid is covered by a finger and raised, the liquid does not leak from the straw. Explain this using ideas of pressure exerted by particles.

Take your finger away from the straw and the downward force of the air pressure on the liquid will be the same as the upward force. These two effects cancel each other out leaving gravity as the dominant force causing the suspended liquid to drop out the bottom.

lol I don't know think u could help me with my mathematics

answer

procedural programming, object-oriented programming

explanation

procedural programming is a type of computer programming language that specifies a series of well structured steps and procedures   within its development period of time. it contains a systematic order of statements, functions and commands to complete a computational task or program. it is centered on creating procedures. while object oriented programming is a programming language that is centered on creating objects rather that actions and data rather than logic.. it has four principles which are inheritance, polymorphism, abstraction and encapsulation
