A+30.0 nc charge is placed at the origin of an xy-coordinate system, and a −25.0 nc charge is placed at the point (3.000 m, −0.0450 m).
(a) determine the magnitude and the direction of the force that the positive charge exerts on the negative charge. use ijk notation for your result.
f =
(b) determine the magnitude and direction of the force of the negative charge on the positive charge.
f=

what is the speed of a softball that travels 20m in 2secs

speed = 20/2 = 10 m/s

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
