a model rocket is made up of a shuttle of mass 20kg, and a fuel tank which has a mass of 4kg when it is empty. when the rocket attains an upwards velocity of 10m. per sec .all of its fuel is used up. At this point ,the empty tank is fired velocity to 13m. per sec .calculate the change in momentum of the rocket without empty fuel tank (60m. per sec upwards)​

the inner core.

good luck: )

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

the old price per ounce is c/4.

the new price per ounce is c/3.6.

the ratio of the old price to the new one is

(c/4)/(c/3.6) = (c/c)×(3.6/4) = 0.9 . . = 9/10 . . "nine tenths" in either form
