What else can I help you with?
Why does air become less dense as you increase altitude?
gravity, denser things go down. -earth science student
Why do sound waves travel faster through iron than air?
Sound waves travel faster through iron than air because iron is a denser medium with particles that are closer together. This allows the sound waves to propagate more quickly through the material compared to air, which has less dense particles that are farther apart, creating more resistance and slowing down the speed of sound.
Why are runaway truck ramps necessary?
The ramps stop or slow down semi-trucks that have lost there brakes. The ramps are made up of gravel or sand or a combo of the two, so that the truck and trailer can sink in.
Are there any websites that can help me find stair ramps?
Stair ramps make it easier for wheelchairs to travel up or down staircases. I was able to find more information on stair ramps here: http://www.disabilitysystems.com/
Will a toy car go faster down a wooden or metal ramp?
If these ramps are the same gradient and length then in theory it should be the metal as its surface is smoother so there is less friction
Cooler denser air is pulled down by?
Cooler denser air is pulled down by gravity but is also pushed down by the rising hot air. This process is called convection.
What things can sink down?
Objects that are heavier than water will sink down, such as metal objects or rocks. Additionally, liquids and gases can sink down into a denser medium, like oil sinking down in water or hot air sinking down in cooler air.
Why time slows down as you start moving faster?
Time seems to slow down because you do more things at once, but it doesn't change.
What happens to the speed of a wave as it travels from a liquid to a solid?
The speed of a wave typically increases as it travels from a liquid to a solid. This is because sound waves travel faster through denser mediums, and solids are denser than liquids. The increased speed is due to the higher elasticity and stiffness of the solid material.
Why flames of a fire rise even though gravity pull thing downwards?
Gravity pulls denser air down, this pushes the lighter hot air, from the fire, up.Gravity pulls denser air down, this pushes the lighter hot air, from the fire, up.Gravity pulls denser air down, this pushes the lighter hot air, from the fire, up.Gravity pulls denser air down, this pushes the lighter hot air, from the fire, up.
Why do things break down faster in warm water?
Things break down faster in warm water because higher temperatures increase the kinetic energy of molecules, causing them to move more rapidly and react more easily. This leads to faster chemical reactions and higher rates of deterioration or decomposition of materials.
Will aluminum foil make things melt faster?
No, aluminum foil does not make things melt faster. In fact, aluminum foil can act as an insulator, which can help slow down the melting process by reducing heat transfer.
