What happens to the pH of distilled water when you add NaOH?
HCl : makes it acidic. it decreases the pH NaOH : makes it alkaline. it increases the pH
What happens when a force act on an object?
When a force acts on an object, it can cause the object to accelerate, decelerate, or change direction. The object's motion is determined by the magnitude and direction of the force applied to it, in accordance with Newton's second law of motion.
What section of the ear makes vibrations stronger?
The three auditory ossicles of the middle ear amplify and transmit the sound vibrations from the tympanic membrane to the oval window.
What makes a voice high or low?
The pitch of a voice is determined by the frequency of vocal cord vibrations. A high-pitched voice results from more rapid vibrations, while a low-pitched voice comes from slower vibrations. Physiological factors like vocal cord length also play a role in determining the pitch of a person's voice.
What happens to the boiling point of water at higher elevations where atmospheric pressure is less?
The boiling point of water decreases at higher elevations where atmospheric pressure is lower. This is because the lower pressure makes it easier for water molecules to escape into the air, requiring less energy to reach the boiling point.
How do objects make sound?
An object makes sound by releasing sound waves that travel through the air, which we call vibrations
What happens to the air pressure when climbing mountains?
as the altitude increases density of air decreases. This makes it harder to breath.
What happens to the pH of distilled water when you add NaOH?
HCl : makes it acidic. it decreases the pH NaOH : makes it alkaline. it increases the pH
What does an object do to make a sound?
An object makes a sound when it vibrates and causes the air particles surrounding it to also vibrate. These vibrations create waves that travel through the air until they reach our ears, where they are interpreted by our brains as sound.
What makes a loud sound?
More vibrations....
What device makes vibrations?
A tuning fork .
What makes the eardrums vibrate?
sound vibrations
A loudspeaker makes sounds by vibrating a cardboard cone what happens to the vibrations of the cone as the sound gets quieter?
As the sound gets quieter, the vibrations of the cardboard cone decrease in amplitude and frequency. This results in less movement of the cone, producing a softer sound.
What happens to the sound as it gets farther away from the object making the sound?
the sod makes a higher pitch
What makes you talk?
the vibrations of the string in your voicebox.(larynx)
What the ear does?
The ear receives vibrations or sound waves in the air through the ear's opening and down the ear canal. These vibrations strike the eardrum, which then makes vibrations. These vibrations are passed to three bones in the middle ear and into the cochlea, which then translates the vibrations into sound.
What kind of motion makes sound?
Vibratory motion makes sound. When an object vibrates, it creates sound waves that travel through a medium, such as air, and are perceived by our ears as sound. The frequency and amplitude of the vibrations determine the pitch and volume of the sound produced.
