Why is a coin able to float on top of water in a glass

1. Surface tension is the result of water molecules pulling inward with a strong attractive force.  

2. The attractive force brings the molecules on the surface of the water close together.

3. The attractive force causes the surface of the water to be drawn toward the water molecules beneath the surface.  

4. Since there are no water molecules above the surface, there are uneven forces. This causes surface tension, allowing the coin to float on the water’s surface.

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
