The size of a black hole, as defined by the size of the event horizon, depends on the mass of the black hole and its electrical charge. The diameter of the event horizon is directly proportional to the black hole's mass. Adding electrical charge decreases the size of the event horizon.
No, they become white dwarves or clumps of burned-out hydrogen and helium that float through space.
Close; the size of the black hole depends entirely on the MASS of the original star.
False. Only the most massive stars will become black holes.
Not all stars do but stars can turn into black holes. Small ones turn in to a black dwarf star when it dies. Medium ones turn in to a neutron then in to a red giant star and then to white dwarf star Large size stars becomes a blackhole..........
black holes
correct, large stars typically become black holes after exploding; our sun is relatively small compared to other stars
Technically yes, realistically, probably not. The best measure of the size of a black hole is the size of the event horizon. That we know of, black holes fall into two general categories: stellar mass black holes and supermassive black holes. The diameter of the event horizon is directly proportional to the mass. Stellar mass black holes range in mass from about 3 to 30 times the mass of the sun, with diameters several miles to several tens of miles. Supermassive black holes are millions to billions times the mass of the sun and are millions to billions of miles across. A black hole with roughly the mass of Saturn would have an event horizon about as wide as an adult human is tall, but there is no known way for an object of that mass to become a black hole.
False. Only the most massive stars will become black holes.
No. They do not have enough mass to become black holes. Depending on the mass they will either become white dwarfs or neutron stars.
False. Medium-sized stars become white dwarfs. Only the most massive stars form black holes.

yes. some black holes are predicted to be the size of an electron.
Yes. Intermediate-mass blackhole is a medium size black hole. Scientists have found stellar black holes and supermassive black holes but there is no prove that Intermediate-mass black type of black holes exist. My opinion is that they do exist because when a black hole is becoming a black hole supermassiveblack hole it will need to go though this stage of intermediate-mass black hole.
there is no exact answer, different black holes have different speeds, but all black holes can crush 1 tonne of metal into a size of a pebble
Except for supemassive black holes, no. Most black holes have about the same mass as a star, but the event horizon is only a few miles across.
black holes
First and the crux here is that, black holes can never become visible(that's why they are called black holes) because the gravity is so insane that it doesn't even allow light to pass! Secondly, if by mistake it was going to become visible then it would appear like any other ordinary star, because black holes have a diameter, on an average, of about 100kms. for more info about blackholes u can refer intermediate physics textbook
By the diameter of their event horizon.
