Create an experiment for this question: How is stomach acid neutralized in the small intestine?
Answer: As we already know it is the pancreas that manufactures enzymes that digest nutrients and releases bicarbonate to neutralize acid chyme that enters the small intestine. An experiment that could be performed to answer this would be to put in a glass flask bicarbonate soda. Then cover it with a balloon to turn it upside down and fill the balloon with the bicarbonate soda. Next you add vinegar to the flask and put back the balloon and slowly pour the bicarbonate soda and see the neutralization reaction that will take place.
I hope it helps, Regards.

The change from a high to a low pitch is a phenomenon known as the Doppler Effect or the Doppler shift. Sounds come in waves and are known as sound waves.
The Doppler Shift or effect is relevant to the location of the person who is hearing the sound. When a person is moving closer to the source of the sound, the wavelengths become shorter and they become low pitch; but when the person moves away from the source of the sound, the wavelengths become longer and become high-pitched.
