Apendulum has 387 j of potential energy at the highest point of its swing. how much kinetic energy will it have at the bottom of its swing?

All of the potential energy = kinetic energy.

So your answer is 665 J

layers of the earth affect the waves and these effects are seen on instruiments such as seimometers

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
