Why is electrostatic force dangerous?
Electrostatic force can be dangerous because it can build up static electricity on surfaces or objects, leading to unexpected electrostatic discharge (ESD) or sparks. These sparks can ignite flammable materials or cause damage to sensitive electronic equipment. In certain conditions, electrostatic discharge can also pose a risk of electric shock to individuals.
Why electrostatic experiment not work well in humidity?
Humidity increases the presence of water molecules in the air, which can interfere with the build-up and transfer of charge in electrostatic experiments. The water molecules can dissipate the charge more easily, leading to poorer results in humid conditions.
What causes an aircraft to build up a static electrical charge?
As the aircraft travels at high speeds through the air, friction between the air and the body of the aircraft create charge. This is why aircraft's have special rubber wheels which contain a conducting material, to release the charge into the ground when they land.
How does electrostatic energy build up during refueling?
Electrostatics is a problem requiring consideration in refueling because of something called triboelectric effect. It's a form of contact electrification. Any time a material comes in contact with another material - let alone moves across it like a person walking across a rug - charges can move. When two materials rub across each other (like fuel passing through a hose), charges can move resulting in a charge buildup. If the materials involved in this process are not good conductors, the charge cannot bleed off, and it will build up where ever the charges can collect. Metal fittings are a good place for that to happen. In aircraft refueling, the first operation is the connection of a ground wire between the aircraft and the refueling vehicle. And the last thing on the checklist is to disconnect that ground wire. The problem is the same "static electricity" we encounter when we pull plastic wrap off a role. The underlying physics is the same - move something across something else, electric charges can move and an electrostatic difference of potential can build up in a nonconductive environment. Even to the point of an electric arc - which can be a disaster in refueling operations. Wikipedia has more information in their article on triboelectric effect, and a link is provided to that article. You'll find it below.
Why does static charge not tend to build up on a conductor?
Static charge does not tend to build up on a conductor because charges on a conductor move freely due to the presence of free electrons. Any excess charge present redistributes itself on the surface of the conductor, neutralizing and eliminating the build-up of static charge.
How can build up of electrostatic charge be prevented?
To prevent the build-up of electrostatic charge, you can use anti-static materials, ground or dissipate charge through conductive surfaces or wrist straps, avoid materials prone to building up charge, and maintain proper humidity levels in the environment. Regular cleaning and avoiding friction between materials can also help to minimize the build-up of electrostatic charge.
Why it is dangerous to touch the knob of aeroplane during flight?
When the aeroplane is in flight, the friction between the moving plane and the surrounding molecules causes a build up of a charge on the plane. This electrostatic force can have the same effect as a current in a wire.

What is ligthing?
Lighting is the deliberate use of artificial light sources to illuminate a space for practical or aesthetic purposes. It can enhance the ambiance, mood, and functionality of a room by providing illumination for activities, highlighting architectural features, and creating visual interest. Good lighting design takes into account factors such as brightness, color temperature, and distribution to create the desired effect.
Why did the wrights build the glider and aircraft?
yes
What is a build up of charges on an object?
The build up of a charge on an object can be referred to as a static build up charge.
What natural products are used to build a aircraft?
Almost no natural products are used in building aircraft
What dangers are present if the aircraft is not grounded as soon as it lands?
Just like rubbing your hand on a balloon, the skin of an aircraft can build up a lot of static electricity due to the aerodynamic friction as the airplane flies. Since the tires are rubber, which is an excellent electrical insulator, and the tires are the only part that contact the ground. It is possible for the aircraft to retain this charge well after landing. Anyone or anything that comes into contact with the aircraft could ground the charge & get a good jolt & probably a spark. Naturally this is of grave concern, as the first thing to touch the aircraft may very well be a fuel hose. The spark generated on discharge could ignite fuel vapors. To mitigate these risks, most aircraft are equipped with "static wicks" which bleed off this static electricity into the air as the aircraft flies. These will be in the form of small rigid plastic protrusions from the trailing edges of the wings and tail surfaces. There may also be a static wick on the landing gear which discharges static charges into the ground on touchdown. Fuel trucks are also equipped with ground-lines which are connected to the aircraft before fueling takes place. Additionally, many aircraft which use glass windshields (as opposed to acrylic) may produce and hold a very dangerous charge in that windshield. When cleaning one of these windshields, it is important to first pour a small amount of water onto the glass to dissipate the charge to the rest of the aircraft, otherwise you may receive a very dangerous electrical shock.
