The potential-energy function U(x) is zero in the interval 0≤x≤L and has the constant value U0 everywhere outside this interval. An electron is moving past this square well. The electron has energy E=4U0.What is the ratio of the de Broglie wavelength of the electron in the region x>L to the wavelength for 0

grav forces affect all objects magnetic forces affect magnetic objects and electric currents

the motion of a pendulum is a classic example of mechanical energy conservation. a pendulum consists of a mass (known as a bob ) attached by a string to a pivot point. as the pendulum moves it sweeps out a circular arc, moving back and forth in a periodic fashion.

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
