A periodic wave (i. e., a wave pattern that repeats itself) is produced in a stretched string by a mechanical oscillator operating at a frequency of 465 Hz. This means that one point on the stretched string is pushed up and down at a regular frequency. The so-called "oscillator" is the source of the repeating waves. The linear density of the string is 0.00140 kg/m and the wavelength of the periodic wave is 0.0700 m.

measure their densities same density, same sub

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
