On october 21, 2001, ian ashpole of the united kingdom achieved a record altitude of 3.35 km (11 000 ft) powered by 600 toy balloons filled with helium. each filled balloon had a radius of about 0.54 m and an estimated mass of 0.27 kg. (a) estimate the total buoyant force on the 600 balloons.

buoyant force = 4.160  kN

Explanation:

given data

altitude = 3.35 km

toy balloon = 600

radius r = 0.54 m

mass m = 0.27 kg

to find out

total buoyant force

solution

we will apply here buoyant force formula that is

buoyant force for 600 = 600 × ρ × g × v    1

here v volume  = 4/3 × π × r³ = 4/3 × π × 0.52³ = 0.5889

and ρ = 1.20 kg/m³

so

buoyant force for 600 = 600 × ρ × g × v

buoyant force for 600 = 600 × 1.20 × 9.81 × 0.5889

buoyant force = 4160.06 N

buoyant force = 4.160  kN

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

it's when something is going so fast it makes a loud noise, breaking the sound barrier, for example: a jet makes a loud noise, not only cause of the jet but because they reached a point where they went so fast that you can year the noise from various parts, kinda like a police car, lets say the car was going   so fast that you hear the siren of the cop car right next to you, but the car is probably a mile a way, it's cos the siren was next to you a few seconds if you understand me
