A vacuum is made of nothing. It is the absence of matter.
Vacuum tubes are typically made of glass or metal. The glass or metal envelope contains electrodes and is evacuated to create a vacuum inside. The electrodes are made of elements like tungsten or molybdenum.
In an auto air system, the vacuum is typically generated by the engine through a vacuum pump or by intake manifold vacuum. The vacuum is used to operate various components such as the HVAC system, brake booster, and emission control system. Loss of vacuum can lead to poor performance of these components.
No, it is theoretically impossible to create a perfect vacuum due to the presence of unavoidable quantum fluctuations at the subatomic level. However, scientists have been able to create extremely high-quality vacuums in laboratory conditions.
the cathode ray tube in an older TV or monitor. valves (vacuum tubes) in older radios or stereos. some stereos and record players are still made with for those who wish. Fluorescent tubes and incandescent bulbs are made with a low pressure not quite a vacuum.
The first vacuum cleaner was invented in 1901 by Hubert Cecil Booth. Booth's invention was a large, horse-drawn machine that was used to clean the floors of shops and businesses.
who made the vacuum tubes
A vacuum is composed of empty space.
The Electrolux PU3450 Central Vacuum is probably the cheapest vacuum ever made.
The only kind of vacuum canister that a Dyson vacuum machine will take is one that is made by Dyson. These canisters are made especially for Dyson, and to date there are no competitors in the market.

The first robotic vacuum cleaner was madde in 2002.
