Yes. The pilot has to obtain atleast a Bronze certificate to pilot the balloon alone.
A barrage balloon is a large helium-filled balloon that is tethered to the ground with steel cables. It is used as a defensive measure to deter low-flying aircraft from attacking ground targets. The cables are intended to damage or destroy the aircraft if they come into contact with them.
depends how big the helium balloon is and how many
It was made out of the light gas gas Helium.
The object that already has helium is most likely a helium-filled balloon. Helium is used to inflate balloons as it is lighter than air, causing the balloon to float.
Helium. The helium gas in the balloon is lighter than the air outside the balloon.
A helium balloon is made by filling a latex or mylar balloon with helium gas, which is lighter than air, causing the balloon to float. The helium gas is sealed inside the balloon, allowing it to stay afloat for a period of time before slowly deflating.
The balloon with helium.
A helium "balloon" is composed of two parts: the SOLID rubber balloon skin, and the GASeous helium. So the balloon part itself is a solid.
When a balloon is filled with helium, it becomes buoyant because helium is lighter than the surrounding air. This causes the balloon to rise and float. The helium gas inside the balloon also increases the pressure, which helps the balloon maintain its shape and stay inflated.
A balloon filled with helium flies because helium weighs less than air.
Helium is lighter than air. hence helium balloon will float in air.
Yes, helium will help a balloon fly. Helium does not affect the direction that a balloon goes, but it will keep it in the air for quite some time.
