The lowest key on a piano plays a note called A0 (27.5 Hz). If you push that key down very slowly and hold it, the felt hammer below won't have enough energy to strike the string but the wool damper, which usually rests on top of the string to stop it from vibrating, will stay lifted leaving the string "open." If you then play an A major chord one octave op, consisting of A1 (55 Hz) - C#2 (68.75 Hz) - E2 (82.5 Hz) - A2 (110 Hz), with a quick, hard strike and sudden staccato release, you will hear a soft, long-lived echo of the chord even though the dampers have stopped vibration in the strings of the chord. What is going on here? Explain in a few sentences.

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 components of a vector are the parts of the vectors that are to each other.

the design of a ski jumping suit involves a trade-off between giving the skiers lift to get higher jumps and ensuring the skier does not face a lot of drag before the jump itself. an expansive suit may to lift the skier higher, but at the same time, it will also increase the air resistance. higher air resistance as the skier goes down the slope limits the speed of the jump. a big suit also increases the risk of losing balance or control, especially if there's a strong gust of wind. while technologically enhanced suits a lot, clothing is not the only factor in a ski jumper’s success. gathering speed while skiing down the slope, ensuring good speed on the ramp, and maintaining good body posture and form in the air all contribute to a ski jumper's success.
