Is this true Light waves do not change speed as they travel from air through water?
no. they slow down.
Why electron travel through the vacuum and not travel through the air?
how electron move in vacuum and not move in air
Which is better for sound to travel solid or air?
Air
If air has pressure why don't we explode?
We don't explode, or implode, due to air pressure because the pressure inside our bodies balances the pressure outside our bodies. This is the normal state. At sea level and standard conditions, air pressure is about 14.7 pounds per square inch. In the non-normal state, such as decreasing or increasing the outside air pressure, our bodies attempt to compensate. Within limits, this is successful, such as going up and down in an elevator or in an airplane. In extreme conditions, such as very deep water, we can implode. In the opposite case, such as in outer space, we can explode.
Would sound travel faster in warm air or cold air why?
The sound travel faster in warm air because the average mean speed of the molecules of air is faster in warm air than on cool air. Sound is transferred by collisions of molecules. Therefore sound waves will travel faster on warm air because collisions of molecules of air in warm air is greater.
How does a parachute travel slowly through the air?
it traps air inside to slow it down
How does air travel when you inhale?
It travels down the trachea to your lungs.
What is the function of government sponsored bodies in travel and tourism?
which are the government sponsored bodies in tourism and travel
Why do hot air balloons travel upward?
The heated air causes the whole balloon to rise. When the air inside the balloon cools down, or when the hot air is let out, the balloon goes down.
Does air pollution hurt our bodies?
Yes it hurt our bodies because it is in the air and we breathe that air.
The sun and all of the planets and other bodies that travel around it?

Which way does air flow in a cooling system if the system is upstairs?
Air flow in an HVAC system is always circular. In the return air grills and out the supply registers. If the unit is upstairs and the ductwork goes down stairs then the supply would travel down and the return would travel up.
Is this true Light waves do not change speed as they travel from air through water?
no. they slow down.
Would striking a steel ball on the moon cause more movement than striking it on the Earth?
No, as long as you do not factor in air resistance, the ball keeps the same inertia on earth as it does on the moon and will therefore resist movement equally on both bodies. If you do include air resistance in your problem then the ball will travel a longer distance on the moon since friction with the air will not slow it down.
In a perfect vacuum, light waves travel at 300,000 kilometers every second. When light waves travel through materials, such as air, they?
slow down.
What is air travel management?
managing air travel
Why do you travel by air?
It's faster to travel by air.
