The drag on the hull of a ship depends in part on the height of the water waves produced by the hull. the potential energy associated with these waves therefore depends on the acceleration of gravity g. hence, we can state that the wave drag on the hull is d= f(rho[infinity],v[infinity], c, g) where c is a length scale associated with the hull, say, the maximum width of the hull. derive the non-dimensional groups for this problem, one of which is non-dimensional drag. hint: choose rho[infinity],v[infinity], c as the basis variables.

think its the third option

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

t = 1/400 h   ⇔ 0.0025 h ⇔ 9s ⇔ 0.15 m

any of the answers are correct.
