Question

Wanda and Marita are drinking bottles of water. Each girl sounds a different musical note by blowing across the top of her bottle. What is a good hypothesis that could lead to new experimentation? It is more fun to play musical notes with carbonated water than with normal spring water If the lid on a bottle is tightly closed then blowing across the top of the bottle will not make a musical note. Blowing across the top of a bottle can make a musical note If there is less water in the bottle, then the note played is lower because there is more air to move around.

Explanation / Answer

The answer is d=If there is less water in the bottle then the note played is lower because there is more air to move around

In the given statement, each of the two girls has a bottle and both of them are producing a different musical note.
This occurs due to differences in the lengh of the air column in the bottle, So, the shorter the air column in the bottle, the higher the frequency and the higher frequency leads to high pitched voice.
