The power that an engine must Exert to accelerate a vehicle in a straight line from rest to a speed of v in a time t 50 watts. How much power in watts must the engine exert to accelerate the same vehicle from a speed of v to a speed of 4v in a time of (1/2)t?

vapour or gas assuming atmospheriv pressure

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

refractve index = sin incidence / sin refraction

one "light year" is the distance that light travels, through vacuum, in one julian year.   that's 365.25 days, of 24 hours each.
