What else can I help you with?
A noisy toy is placed in a glass jar. All the air is then slowly removed from the jar. How does this affect the sound you hear?
As the air is removed from the jar, the sound of the toy will become quieter and eventually inaudible. This is because sound requires a medium (such as air) to travel through, and with no air in the jar, there is no medium for the sound waves to propagate through.
Why can't you hear whoosh sound when you open the jar of pickle or peanuts at the second time or can you hear the sound at the second time?
Jars of peanuts, pickles, spaghetti sauce and others, are vacuum sealed at the manufacturing plant. That means that all the air is sucked out of the jar at the moment that the lid is screwed on. This is done to prevent bacterial growth. the whoosh sound we hear is the outside air rushing back into the jar when we open it for the first time. When we close the jar, there is always some air that stays trapped in the empty space under the lid. Since air is already present in the jar when we open it again, no air needs to rush in and no whoosh sound is produced.
Why cant you hear a bell inside of a vacuum jar?
Sound is mechanical energy, and the energy of the sound is transferred into the medium through which it is travelling. As the energy of sound is carried by the medium, the vacuum of space will not support a sound wave.
If a bell is ringing in a bell jar you cant hear it when the air is pumped out but you see it what differences in properties of sound and light does this indicate?
That sound cannot move through a vaccum.
I you put an alarm in a vacuum jar you can't hear it why?
In a vacuum jar, there is no medium for sound waves to travel through, so the alarm cannot be heard. Sound waves require a medium, such as air, to propagate and reach our ears. Without a medium, there is no way for the sound to travel and be perceived.
How did Robert boyle demonstratebthe sound waves cannot travel through empty space?
Robert Boyle demonstrated that sound waves cannot travel through empty space by conducting experiments using a vacuum. He used a bell jar and a vacuum pump to remove air from the jar, which contained a ringing bell. As the air was evacuated, observers noted that the sound of the bell diminished and eventually became inaudible, illustrating that sound requires a medium, like air, to propagate. This experiment provided clear evidence that sound cannot travel in a vacuum, as there were no air particles to transmit the sound waves.
If an alarm clock is in a jar filled with air what happens if all the air sucked out of the jar?
The alarm would be much quieter, as sound can't travel through vacuum. But if it's a mechanical alarm clock then vibrations would be transferred from the clock to the jar and then to whatever the clock is standing on , and you'd probably be able to hear some of that.
What is the weight of an empty jam jar?
The weight of an empty jam jar can vary depending on its size and material. On average, a small empty jam jar may weigh around 100-200 grams, while a larger jar may weigh 300-500 grams.
How do you use a 3 and 5 quart jar to measure 1 quart?
Fill 3 qt jar, and empty into 5 qt jar. Fill 3 qt jar again, and empty 2 qt into 5 qt jar, 1 qt left.
When the air in a bell jar containing a ringing bell is removed the sound decreases. why?
When the air is removed from the bell jar, there is no medium for the sound waves to travel through, resulting in the decreased sound. Sound waves require a medium, such as air, to transmit vibrations. Without air in the bell jar, the sound waves cannot propagate as effectively, leading to a decrease in the sound.
Where does water in the jar come from when an empty jar is left outside overnight?
Rain or Condensation
Is jar long vowel?
No, the word "jar" does not have a long vowel sound. The "a" in "jar" is pronounced with a short vowel sound, like in "cat" or "map."
