How do unbalanced forces affect a hot air balloon?
Unbalanced forces can cause a hot air balloon to accelerate in the direction of the stronger force. For example, if the upward buoyant force is greater than the downward force of gravity, the balloon will rise. If the forces are equal, the balloon will remain at a constant altitude.
What happens to the balloon as you pull the rubber sheet downward?
As you pull the rubber sheet downward, the balloon inside will be compressed and shrink in size due to the decreasing volume of the space within the rubber sheet. The air molecules inside the balloon will get more tightly packed together, causing the pressure inside the balloon to increase.
What happens when an air filled balloon is left with its mouth downward and allowed the air to escape?
When an air-filled balloon is left with its mouth downward and the air is allowed to escape, the balloon will collapse and shrink in size. This is because the air pressure inside the balloon is greater than the atmospheric pressure outside, causing the air to rush out until the pressures equalize.
As a balloon rises does the presure inside the bag of balloon increases or decreases?
As a balloon rises, the pressure inside the balloon decreases. This is because the atmospheric pressure outside the balloon decreases with altitude, causing the balloon to expand as the pressure inside remains relatively constant.
What happen to the balloon when you pull the rubber sheet down ward?
When you pull the rubber sheet downward, the air inside the balloon gets compressed, causing the volume of the balloon to decrease. The pressure inside the balloon increases, causing it to shrink in size.
Why does a helium-filled balloon rise to a certain altitude in the atmosphere and float there instead of rising further?
The helium-filled balloon rises to a certain altitude in the atmosphere and floats because at that point, the buoyancy force (upward force) of the helium inside the balloon equals the gravitational force pulling the balloon downward, resulting in equilibrium. This balance of forces causes the balloon to stay at a stable altitude instead of rising further. Additionally, the surrounding air pressure and density decrease with altitude, affecting the balloon's ability to rise further.
What might cause a balloon blown up at low altitude to burst if it is taken to a higher altitude?
at altitude the balloon's external air pressure has been greatly reduced, often expanding the balloon to the bursting point.
Is motion of a balloon ascending at a rate of 14 meter per second is accelerated or decelerated?
since the balloon is moving up with a constant speed it is not accelerated or decelerated
How do unbalanced forces affect a hot air balloon?
Unbalanced forces can cause a hot air balloon to accelerate in the direction of the stronger force. For example, if the upward buoyant force is greater than the downward force of gravity, the balloon will rise. If the forces are equal, the balloon will remain at a constant altitude.
What measures cloud altitude and direction?
a weather balloon
What is the maximum altitude of a barrage balloon?
The maximum altitude of a barrage balloon is typically around 15,000 feet (4,500 meters). This height allows the balloon to effectively discourage low-flying aircraft from targeting ground units.
How does the altitude effect the size of a balloon?
As the external pressure drops with increasing altitude, balloons generally expand with height.
What happens to the hot air balloon when it reaches an altitude of 10000 meters?
the air pressure outside of the balloon decreases.
What is a balloon ballast?
A balloon ballast is a weight attached to a balloon to control its altitude or position. By adjusting the amount of ballast on board, operators can regulate the balloon's ascent or descent by lightening or increasing the weight of the balloon.
Would there be more air pressure in a balloon at sea level or high in the sky?
provided the balloon has not reached its elastic limit (it has burst!), the air pressure inside and outside will essentially be equal. [The pressure inside will be slightly less, which is where the lift comes from.] But even at altitude, the pressure will be approximately equal in and out, for at altitude, the balloon will have swelled, thus reducing the internal pressure. It will eventually reach an altitude at which the internal pressure and the external pressure will be equal, and the balloon will have reached maximum expansion. Filled at sea level, a balloon will seem empty and floppy, and very tall and thin. At altitude the balloon will fill out as the external pressure reduces.
What is the craft that uses heat to gain altitude?
A Hot Air balloon.
A student throws a water balloon vertically downward from the top of a building The balloon leaves the throwers hand with a speed of 6.00 ms Air resistance may be ignored so the water balloon is?
