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?

If there is less water in the bottle then the note played is lower, because there is more air to move around. This is one good hypothesis that could lead to a new experiment.

Hope that helps! ★ If you have further questions about this question or need more help, feel free to comment below or post another question and send the link to me. -UnicornFudge aka Qamar

Answer:

If there is less water in the bottle, then the note played is lower because there is more air to move around.

Explanation:

We know that sound waves are mechanical waves, because they only propagate through an elastic and deformable material medium. It is common to hear various types of sounds in our daily lives, and this feature is directly linked to the frequency of sound.

With this we can conclude that depending on the amount of water put into the bottles, when we blow at the top of these bottles a kind of sound will be produced. The less water the lower, the sound comes out, because there is more air for the sound to move. And the more water in the bottle, the higher the sound will be.
