Which invention replaced vacuum tubes in computers?
Transistors were first developed in 1947 by Bell Telephone laboratories. They replaced vacuum tubes, which were big, bulky, costly, and unreliable. Transistors are most often used to regulate the flow of an electrical current and to switch electricity on and off.
A vacuum pump is used for what?
Vacuum pumps are pumps designed to remove or displace gases such as oxygen, or liquids, such as milk. Vacuum pumps are used in a variety of different settings. Milk pumps, both bovine and human, use a vacuum pumps. Trash compactors, vacuum sealers, and even certain types of microscopy uses vacuum pumps.
What is vacuum measured in?
vacuum is measured in pressure. To get a vacuum you need a negative pressure. that would be inches of mercury hg
Vacuum in the doubled-walled vacuum bottle takes care of heat flow by?
no
Measuring a final system vacuum is done with the?
system isolated and the vacuum pump turned off.
Is there air in a vacuum?
A Vacuum is the absence of air. So no, there is no air in a vacuum.
Who is the creator of the vacuum?

What do you call an absence of atmosphere?

What are the properties of electricity in a vacuum?
In a vacuum, electricity can still flow as electrons move through the space without any obstacles. However, the absence of air or other particles means that there is no medium for the electricity to interact with, so it behaves differently compared to in a material medium. This can result in unique phenomena such as the emission of light or the creation of electric arcs.
What is the scientific definition of vacuum?
an absence of matter
What is the complete absence of matter?
No, the absence of matter would be a vacuum, which is quite different from a black hole. A regular black hole has a fairly large amount of mass (which is basically the same as matter) in a small space.
What is policy vacuum?

Whats is definition for vacuum?
Absence of air or suction action.
What term describe the absence of molecules in a given space?
Vacuum.
What absence of matter such as air?
A vacuum is the absence of matter, such as air. In a vacuum, there is no air or other gas molecules present, which can create unique challenges for conducting experiments or maintaining certain conditions.
