How come that they say its dangerous to stand under a tree when lightning strikes but you never see lightning strike a tree?
if you are in a field and there is one tree lightening strikes the tallest object around and if you are under that tree you will feel the effects of that strike or part of the tree could break of where lightening hits and fall on you. if your in a field and lighening starts to strike get as low to the ground as you can till you can seek cover
Does lighting strike cell towers?
A cell tower can receive multiple lightning strikes in just one year, but due to the construction, the energy received from the lightning bolt is transferred to the soil at the base of the tower. Cell towers, like any tall metallic object, is a beacon to lightning and the higher the tower is in height, the more susceptible it is to receive the strike.
What kind of charge can move from object to object?
Electrons can move from object to object. Electrons have a negative charge. So if an object is determined to have a positive charge, then some of the electrons have moved from the object to somewhere else. Something with a neutral charge has the same number of electrons [-] and protons [+]. If electrons [-] leave, then there will be more protons, and a net positive charge. If an object gains electrons, then the object has a net negative charge.
Why lightning shows an affinity to metals. After lightning strikes a place it is found to sort of seek metal objects.Some times it makes holes on mud walls to connect to a metal object inside.Why?
The atoms in metals are not connected to a peticular atom so they are allowed to travel without being stopped throughout the material. This creates a conductivity to electricity. Lightning tends to head twoards object with the most conductivity thus being metal. This is also why being in a car is the safest place to be in during a lightning storm. the lightning will travel through the metal frame around the car and if im not mistaken leave through the ground (the tires) in the end not harming you.
What episode does Aang get struck by lightning?
Season 2 Episode 20
What is the environmental impact of the lightning rod?
A lightning rod is designed to protrude above the highest point of a building. A lightning strike will (hopefully) strike the rod, rather than damage the building itself. The charge will travel safely to earth along a metal cable fixed between the rod and the ground.
What happens when light strikes a transparent body like glass?
Whether the object struck by lightning is transparent or not should not make much difference.
Is it true that lightning strike only twice?
Nope - lightning can strike the same place multiple times if the object presents enough ionic attraction to ground the charge.
What happen to an object wirh a positive charge and an object with anegitive charge?
Two objects like this will tend to attract each other. If the difference in charges is large enough then a discharge (similar lightning) might occur.
How does a lightning rod work?
In addition to providing a conducting path to ground in case a lightning strike occurs, lightning rods also reduce the number of large lightning strikes by reducing the static charge build-up in the atmosphere around the building. The pointed end of the rod creates an attraction point for the excess charge and siphons it to ground, reducing the charge difference between the cloud and the building.If you get a chance to deal with a small Tesla coil or small static generator, set up a situation in which sparking is occurring between a broad object (like a sphere) and the coil/generator . Then introduce a grounded thin rod (or some other grounded pointy object). the sparking will stop and there may be some micro-lightning (and soft crackling sound) around the point.Basically, the pointy grounded rod creates smaller, lower energy lightning to prevent the huge damaging strikes.
If lightning strikes a river how long does it travel?
lightning wouldn't hit a river. . . lightnings strike objects that are nearest to it or the highest/tallest object connected to the ground. . . I'm pretty sure that there are a lot more objects that are more likely to be struck by a lightning rather than a river. . .
Where would you go in a severe thunderstorm if you could not go inside?
you would want to stay away from trees and anything tall. lightning strikes the tallest object in a field
When the object is charged by contact what kind of charge does the object have compared with that on the object giving the charged?
When an object is charged by contact, the object getting the charge has the same charge compared with that of the object giving the charge. so if the object giving the charge has a positive charge, so does the object getting the charge
What occurs when light strikes a transparent surface?
[object Object]
What devices protect planes from lightning strikes?
All commercial planes are equipped with a faraday cage. If lightning were to strike it, the lightning bolt would be routed around the plane and down, without making contact with the inside of the plane. It's like a water drop rolling down a solid object, then falling off it at the bottom.
