An hot air balloon i think.
What else can I help you with?
What does sound most slowly travel through a metal pole a wood block a pool of water or an area of cool air?
Cool air.
Can light travel through air?
yes. if light didn't travel through air, then you wouldn't be able to see anything!
What kind of sound waves do vacuums produce?
The vacuum does not produce sound waves nor, can sound waves travel through them. A sound wave needs something to travel on/through, such as air. A vacuum doesn't contain any particles required for sound waves.
Can x-ray travel through air?
Yes, x-rays can travel through air, but some of the energy is absorbed by the air molecules as they pass through. This is why x-rays are typically used in a controlled setting with protective equipment to minimize exposure to surrounding tissues.
Does helium dissipate from balloons?
yes because helium needs air around it under it in it on it to float and stay alive, but it doesn't.
Name something that needs to travel slowly through air how does it manage this?
A skydiver - he uses a parachute that slows him down as a result of air resistance acting on the surface of the parachute
How does a parachute travel slowly through the air?
it traps air inside to slow it down
Can sound travel through rocks?
Yes it can cause sound waves can travel through solids,liquids,but slowly in gases and air
Can sound waves travel through rocks?
Yes it can cause sound waves can travel through solids,liquids,but slowly in gases and air
Which of these can sound not travel through?
Sound cannot travel through vacuum. It needs a medium, such as air, water, earth, etc.
Why does sound travel more slowly through air than through a solid?
Air molecules are much, much farther away from each other in air than they are in water.
Explain why cant sound travel through vacuums?
there is no air in a vaccum. and sound needs air for the sound waves to travel through.
What does sound most slowly travel through a metal pole a wood block a pool of water or an area of cool air?
Cool air.
There are many objects in the solar system and the universe that make noises why can we never hear any of them?
Sound needs air to travel through, and space has no air.
Sound will NOT travel through?
Sound needs a matter based medium, so it will not travel through vacuum.
Do sound waves travel slowly through iron?
That completely depends on what "slowly" means to you.Sound propagating through iron is quite slow compared to the speed of lightin vacuum, but is substantially faster than the same sound in air.
Do Light waves travel more slowly through air and water?
Light waves travel faster through air than through water because air has a lower refractive index than water. This means that light waves experience less bending (refraction) in air compared to water, allowing them to move faster.
