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
What else can I help you with?
What is the effects of variations of pressure on the speed of sound in gase?
The speed of sound in a gas is influenced by variations in pressure, but primarily depends on the gas's temperature and molecular composition. In an ideal gas, when pressure increases at a constant temperature, the speed of sound remains relatively unchanged because both density and stiffness increase proportionally. However, at constant pressure, an increase in temperature results in a higher speed of sound due to reduced density. Thus, while pressure changes alone have a limited direct effect, they interact with temperature to influence sound speed.
What happens to a planet's speed when it is more distant from the sun?
The planet's speed is reduced.
What is the fan speed relationship to suction pressure?
Generally, as fan speed increases, suction pressure tends to decrease. This is because increased fan speed results in greater airflow across the evaporator coil, which enhances heat transfer and cooling efficiency, leading to lower suction pressures. Conversely, decreasing fan speed can lead to higher suction pressures due to reduced airflow and heat transfer capabilities.
Why does catalyst affect reaction speed?
The activation energy is reduced.
When the wind doubles does the pressure in the sails increase 8 times?
When the apparent wind speed is doubled, the pressure on the sail is quadrupled. That is because the pressure on the sail (or the side of your house or a billboard sign) is proportional to the square of the speed of the wind. If the wind speed triples, then the pressure goes up by a factor of nine, because three squared is nine.
How are speed and presure of fluid related?
The pressure exerted by a fluid is reduced as its speed increases.
When the speed of a fluid increases the pressure decreases when speed of a fluid decreases the pressure increases is called?
This is known as Bernoulli's principle, which states that an increase in the speed of a fluid is accompanied by a decrease in pressure, and vice versa. It explains the relationship between velocity and pressure in a moving fluid.
How does changing the speed of a fluid affect it's pressure?
According to Bernoulli's principle, as the speed of a fluid increases, its pressure decreases. This means that if the speed of a fluid is reduced, its pressure will increase. The relationship between speed and pressure in a fluid is inversely proportional.
Why does the pressure of moving gas decrease speed?
The pressure of moving gas decreases speed because as the gas expands into a larger volume, there is less pressure pushing on the gas molecules. This reduced pressure allows the gas molecules to spread out and move more freely, decreasing their overall speed.
Show by an activity that high speed winds by accompanied by reduced air pressure?
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.
Will fluid speed up as it passes into constricted pipe because of the pressure difference?
Yes, fluid speed will increase when passing into a constricted pipe due to the conservation of mass principle, known as the continuity equation. As the pipe diameter decreases, the fluid must speed up to maintain the same flow rate. This increase in fluid speed is accompanied by a decrease in pressure.
What is the effects of variations of pressure on the speed of sound in gase?
The speed of sound in a gas is influenced by variations in pressure, but primarily depends on the gas's temperature and molecular composition. In an ideal gas, when pressure increases at a constant temperature, the speed of sound remains relatively unchanged because both density and stiffness increase proportionally. However, at constant pressure, an increase in temperature results in a higher speed of sound due to reduced density. Thus, while pressure changes alone have a limited direct effect, they interact with temperature to influence sound speed.
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.
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 the body is reduced to half, its kinetic energy would decrease by a factor of four. This is because kinetic energy is directly proportional to the square of the velocity of the object. So, reducing the speed by half results in the kinetic energy being reduced by a factor of four.
What happens to a planet's speed when it is more distant from the sun?
The planet's speed is reduced.
