An astronaut leaves earth in a spaceship at a speed of 0.96 c relative to an observer on earth. the astronaut's destination is a star system 14.4 light-years away (one light-year is the distance light travels in one year.) according to the astronaut, how long does the trip take?

t=4.2 years

Explanation:

velocity v= 0.96c

destination star distance = 14.4 light year

According to the theory of relativity length contraction

putting values we get

now distance the trip covers

D= vt

t= 4.2 years

so the trip will take 4.2 years

explanation:

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
