1. The distance between the crest of a water wave and the next trough is 2 m. If the frequency of a particular
wave is 2 Hz, what is the speed of the wave? (a) 4 m/s
(b) 1 m/s (c) 8 m/s (d) 2.m/s (e) impossible to deter-
mine from the information given

answer; (arch); good luck

molecules are free to separate from each other and will take on the shape of the container. molecules move completely at random and high speeds. they vibrate in a fixed position and do not move around much. molecules expand to the edge of their container.

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
