Show by an activity that high speed winds by accompanied by reduced air pressure?
Abhinav11aquarius
crumple a small piece of paper into a ball size smaller than the mouth of the empty bottle.hold the empty bottle on its side and place the paper ball just inside its mouth.now try to blow on the ball to force it into the bottle.try the activity with battles of different sizes.
when we blow into the mouth of the bottle,the air near the mouth has higher speed. this decreases the pressure there . the air pressure inside the bottle is higher than near the mouth.

How are fluid speed and fluid pressure related?
As the speed of a fluid increases, the pressure within the fluid decreases.
How is wind speed related to pressure differential?
wind speed means how fast wind goes. the more pressure, the faster the wind. :)
How does barometric pressure change effect wind speed?
cause.
What characteristics do all air masses have in common?
they have changes in temperature, pressure, wind speed, and direction and humidity.
What were the two factors that caused differences in wind speed?
There are two factors that cause differences in wind speed. They are differences in pressure and differences in altitude.
How are speed and presure of fluid related?
The pressure exerted by a fluid is reduced as its speed increases.
How do you prove that high speed wind is accompanied by reduced air pressure?
This happens because when you blow air over the paper,the air pressure above the paper reduces.The air pressure below the paper remains the same.As the pressure below the paper is greater than that above the paper it pushes the paper up.The faster the air moves ,the more is the drop in pressure in that region
As the speed of a rolling ball is increasing,the increasing speed is accompanied by?
momentum As the speed of a rolling ball is increasing, the increasing speed is accompanied by: a. increasing momentum.
What happens to the kinetic energy of a body if its speed is reduced to half?
If the speed of a moving body is reduced to half, its kinetic eneergy is reduced to 1/4 .
How do you get the check engine and reduced speed light off?
By having the problem repaired that caused the light to come on and speed to be reduced.
How does the use of a hyperbaric chamber speed up the elimination of CO from the body?
In hyperbaric therapy at three atmospheres of pressure, the half-life is reduced to 20-25 minutes.
What happens to a planet's speed when it is more distant from the sun?
The planet's speed is reduced.
What is speed endurance?
refers to duration of activity.
Is sound produced when there are increases in pressure or oscillations in pressure?
The speed of sound does not change with atmospheric pressure. The speed of sound changes with temperature.
Why does car skip at a certain speed?
At what speed does it occur? Is it accompanied by shaking? Check ur plugs, wires, and Ignition coil packs
What happens to the centripetal force if the period is increased?
In circular motion the centripetal force is proportional to the speed squared. The speed is the circumference divided by the period. So if the period is increased the speed will decrease and the centripetal force will decrease. For example if the period is doubled then the speed is reduced by one half and the speed squared is reduced by one quarter, and so the centripetal force is reduced by one quarter.
What is the relationship of speed of sound to the atmospheric pressure?
There is a relationsship of speed of sound to the temperature but not to the atmospheric pressure.
