Does a black hole ever get full?
According to current theory, a black hole, if it exists, begins its life full,and nothing that falls into it ever leaves it.
Why cant there be hole current in the conduction band?
In a semiconductor, the conduction band is filled with electrons, which are negatively charged. Holes represent the absence of electrons in the valence band, not in the conduction band. Since the conduction band is typically occupied by electrons, it cannot have holes; instead, holes exist in the valence band where electrons are missing. Therefore, while there can be free electrons in the conduction band, holes are specifically a feature of the valence band.
How do you know black hole exists?
They know because the effect the black hole has on other matter.
How strong is a white hole?
There is no evidence that such a thing as a "white hole" exists, or that it even can exist. The theory of what properties such a white hole would have is not on a firm foundation, either.
What is more dense black hole or star?
A black hole is more dense. In principle, the black hole exists all at one point. So its volume is zero, and its density is infinite.
What happens when electrons in conduction band loses its energy and falls to a hole in the valence band?
The energy leaves as either a photon or phonon.
Why do Japanese coins have holes in the center?
Back then, when wallets didn't exists the Japanese needed a way to carry their money so, because of the hole in the middle of the coin, they were able to hold all their money on a string kind of like a bracelet.
What happens when ice is added to canola oil and how does the temperature change?
A black hole is formed and no temperature exists
Where can you find a white hole?
Only in theoretical science: there has been no physical proof that one exists anywhere.
What is the super-massive structure that exists in the middle of nearly all galaxies?
A super massive black hole.
What is recombination in electronics?
Process by which a conduction band electron gives up energy (in the form of heat or light) and falls into a valence band hole.
Why bjt is bipolar?
BJT stands for bipolar junction transistor because it is composed of two types of semiconductors (P and N-type) rather than just one type like a unipolar transistor. This allows for both electron and hole current flow in the device, giving it its bipolar characteristic.
