A black hole can have a positive charge, negative charge, or no charge. It all depends on the charges of the material that fall into it.

In a photocell what is the charge of a hole?

In a photocell, the charge of a hole is positive. Holes are essentially empty spaces in a crystal lattice where an electron has moved away, leaving behind a positive charge that can move through the material similar to a positively charged particle.


Is negative black hole present?

There is no such concept of a negative black hole outside the fictional computer game involving Sentry Catapult.


What part in the atom moves when electric charge is transfers from one atom to the other'?

When there is an electrical current, there is a movement of some charged particle. This may be any kind of particle - an electron (negative), a hole (positive), an ion (positive or negative), or some other particle.


Where is the relation between the holes and proton like the positiv charge?

proton has the positive charge and holes came in the picture during the discovery of diodes. It is also important in the phenomenon of drift velocity(electricity related process) and scientists consider that when a electron moves from its place to the other side of diodes a vacant place is created where there was electron before so that vacant site is referred as hole and it is taken as having positive charge because as the electrons move the other side of diode more holes are created as deficiency of electrons and that side of diode behaves as positive side and other side of diode as the accumulation of negative charges (electron) behaves as negative side.


Is a black hole an example of negative pressure?

Yes, black holes are an example of negative pressure. This is because they exert gravitational force so strong that nothing, not even light, can escape from them, creating a region of extreme gravitational pressure.

Why hole has positive charge?

A hole in a semiconductor has a net positive charge because it represents the absence of an electron, which has a negative charge. When an electron moves from its position to fill the hole, it leaves behind a positively charged location or "hole." This movement of electrons creates a current flow in the material.

Why do holes migrate in direction of the applied electric field?

It might help to consider a hole as a positive particle (or rather, quasi-particle). Any positive particle gets attracted by a negative charge, and repelled by a positive charge. Of course, in reality it is the electrons that move, to fill out the hole - but the effect is the same.

What black hole property determines the schwarzschild radius of a black hole?

The black hole property that determines the Schwarzschild radius of the black hole is that it has mass but no angular momentum nor electric charge.

How do you decide which number is greater when one number is negative and one number is positive?

ANY positive number is greater than any negative number. Imagine you are digging a hole, and piling up the dirt you remove from the hole. The hole represents negative numbers- it goes lower than the surface. The piled up dirt represents positive numbers- it is higher than the surface. The surface is zero- neither positive or negative.


What are the 3 characteristics of a black hole?

Three key characteristics of a black hole are its mass, charge, and spin. The mass determines the gravitational pull of the black hole, affecting how it interacts with surrounding matter. Charge refers to the electric charge of the black hole, which can influence its electromagnetic interactions. Spin describes the rotation of the black hole, affecting the space-time geometry around it and leading to phenomena like frame-dragging.


Can positive energy escape from a black hole?

Sorry, no.


When an electron is displaced in a semiconductor the hole thats left behind is?

a. attracted to the negative terminal of the voltage source as an electrons leave its orbit it leave a hole which is promptly filled by another electron. so as electron flow one way the holes flow the opposite direction. in electronics current flow from positive charge to a less positive chargeclassified as a "hole". Although it doesn't really *exist, it is thought to have the same charge as an electron but opposite polarity.

What positive influences did black holes do on science and society?

Please note that the closest known black hole is at a distance of 3000 light-years. Such a black hole cannot directly "have a positive influence". The supermassive black hole in the center of most galaxies is believed to have an important role in the galaxy formation - so it may have had an important influence in the remote past.
