An 800-khz radio signal is detected at a point 8.5 km distant from a transmitter tower. the electric field amplitude of the signal at that point is 0.90 v/m. assume that the signal power is radiated uniformly in all directions and that radio waves incident upon the ground are completely absorbed. what is the average electromagnetic energy density at that point?

close lines strong magnet less close weaker

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
