What are the differences between a vacuum breaker and a SF6 gas circuit breaker breaker and a sf6 gas circuit breaker?

A vacuum breaker uses a vacuum to extinguish the arc when interrupting a circuit, while a SF6 gas circuit breaker uses sulfur hexafluoride gas. SF6 gas circuit breakers can handle higher voltages and currents compared to vacuum breakers. SF6 gas circuit breakers are also more environmentally harmful due to the greenhouse gas SF6, while vacuum breakers are considered more eco-friendly.


How playing paintball relates to newtons first law of motion?

You can relate it to the law of " an object will remain in motion unless acted upon another force". So, if you fire a paintball, in a vaccume it should continue forever. However, due to the air resistance and say a player in front of you, the paintball will stop.


If electro magnetic waves are produced by motion of electrically charged particles then how could they travel in vaccume?

good question, unfortunately nobody really knows! Initially, scientists assumed it was travelling through some undetected medium which they called the ether. But no one managed to prove it. Now scientists just say that it is a self-propagating wave of oscillating electric and magnetic fields, so it doesnt need a medium to travel through.


What is vaccume freeze drying?

Under reduced pressure, under carefully controlled conditions, ice sublimes - it goes straight from ice to vapour - no liquid water. It is very useful for drying almost anything, but especially for anything that would be damaged by heating or boiling the water off. That is vacuum freeze drying - the name is often used without the "vacuum" included.

Why does a 1995 s10 blazer shut off when brakes are pressed?

Is your brake pedal hard ? If so replace the power brake booster. It sounds like you have a major vaccume leak in the booster when you apply the brakes. Power brakes work off of engine vaccume. If the dieafram is leaking vaccume when you apply the brakes it leans the engine out. ( creates a major vaccume leak ) and engine dies. Hope this helps.
