A motorcyclist is moving 24.5 m/s toward a stationary siren, and
hears an 894 Hz sound. What is
the frequency of the siren when
the cyclist is stationary?
(Hint: 894 Hz is the Doppler-shifted
frequency.)
(Speed of sound = 343 m/s)
(Unit = Hz)

answer: (431,2)

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
