The impedance mismatch is such that two identical waves are created at the end of the wires which are in anti phase to both the incoming current and the current launched into the room. Hence both are cancelled. However, the voltages are not cancelled and the voltage wave does escape into the room. It is responsible for hum that audio equipment is prone to unless screened.
Someone said: "Because it needs a path way in which to travel". But it has one: the air. The point is that the wire to air mismatch is so huge that the cancellation I referred to takes place and the overall current flow is zero. Talk about pathways or conductors and insulators is only a simplified way of looking at the flow of electromagnetic energy.
Anyway James Thurber's aunt reckoned it did escape and caused all sorts of problems. The escaped energy I mean, though I dare say his aunt caused a few problems as well.
The strong gravitational pull of the gas giants, such as Jupiter and Saturn, keeps the gases from escaping into space. The immense mass of these planets creates a powerful gravitational force that holds the gases in their atmosphere. Additionally, the presence of a magnetic field around these planets also helps in trapping the gases and preventing them from escaping.
The planet's strong force of gravity holds the atmosphere down and stops it escaping. Atmospheric gases have masses, and the Earth's atmosphere has a mass of about 1.2 kg per cubic metre.
gravity keeps the gas giants planets gases from escaping so they have thick atmosphere
Electrical wires are surrounded by nonmetal materials, such as rubber or plastic, to provide insulation that prevents electricity from escaping, reduces the risk of electric shock, and protects the wires from damage. Metal materials can conduct electricity, making it unsafe for wires to be exposed or surrounded by metal.
It is called a socket or base. This keeps the bulb securely in place and allows electricity to flow directly to the bulb.
The planet's gravity.
An insulator is an object that does not conduct (allow something to flow through it). It is used typically in heat or electricity applications. For example, insulation in a house, keeps heat from escaping outside.
An insulator doesn't keep electricity in anything. Electricity follows metals, period. To put it another way, It's like you wearing a glove to prevent heat or cold to touch your skin, the plastic insulation on wire keeps the electricity from touching anything outside the metal it is flowing through.
Insulation and reflection.
It keeps the sun's warmth from escaping by the greenhouse effect
A cap that keeps the gas and gad vapors from escaping from the fuel tank.
If it's a fluid filled hub, yes.
Because it traps the heat that comes from your body from escaping, so you have more heat so it keeps you warm.
prevents it from escaping into the surrounding environment. Insulators are materials with high resistance to electrical current, helping to maintain the flow of electricity along the intended path. Without insulators, there would be a risk of electric shock or short circuits.
gravity keeps the giants planet's gasas from escaping
A switch. Insulation keeps the electricity from a short circuit.
