Select a musical instrument. research the instrument and explain how it works in terms of sound production and resonance. describe how a musician can vary the pitch and loudness of the notes. explain why different types of musical instruments sound different, even though they play the same notes.

Explanation:

Xylophones is an instrument which has wooden bars attached to mallet.

When bars are hit, a sound is produced which resonate in the wooden boxes.

These wooden bars are of different sizes thus there pitch different from each other.

The longer the bars, more time the sound will be there hence lower will be the pitch.

As musical instruments are different in structure, they have different nature and produce different sounds.

not really sure but thinking 1.54 mm/us

answer would be letter choice (a),   a ball resting on a shelf. would be another example of potential energy   >   stored energy > not moving.

a ball spinning on a finger   >   kinetic energy > moving energy

a ball rolling on the ground   >   kinetic energy   > moving energy

a   ball flying through the air   > kinetic energy   >   moving energy

hope that                                         : )
