Enharmonics
A leap in music is when the interval between one note and the next is larger than a step (or 2nd). An example is C to E.
A dotted quarter note. (One beat for the quarter note and half a beat for the dot.)
A conch shell when blown produces a very loud booming blast, a little like blowing one note very loudly on a trumpet.

The answer is a clock - it moves its hands but doesn't make a sound, while a bell makes a sound but stays in one place.

No. A one beat note is called a crotchet and a two beat note is called a minim.
If your finger is just lightly held over a guitar or bass string it is called a "muted note". In order to produce a sound on a guitar or bass you must either have you finger placed firmly on one of multiple frets. When no frets are held that is called an open note, or string.
If a note has a frequency of 400 Hz, it means that there are 400 sound waves produced in one second. The frequency of a sound wave is the number of complete waves that pass a point in one second.

No, the speed of sound is constant in a medium, so the speed of sound heard by an observer staying in one spot does not change if the source of the sound is moving. The frequency and wavelength of the sound may be affected by the motion of the source, but not the speed.
The term to describe the relationship of multiple pitches contributing to the total sound of one single note is "timbre" or "tone color."
Note length is a relative value, so the physical length of the sound would depend on the tempo of the concrete piece of music. If we take tempo largo (about 44-52 beats per minute), one quarter note would last 60/44=1,36 seconds. So one 128th note would sound 32 times shorter, that is a little more that 4 milliseconds.
They are called waves.
Stagnant air.
