What is the escape velocity from the surface of a typical neutron star? How does that compare with spd of liht

Question

ay yi yi.. I don't understand this

Answer 1

A typical neutron star has an escape velocity of about 40% to 66% of light speed.

Answer 2

The escape velocity of an object from the Gravitional mass(in this case a star mass)is calculated From the following Equation:

Ve^2 = 2 G x Mg / Rg

Where Ve is the escape velocity and G is Newton gravity Constant and Rg is the Radius of the Gravitational mass.

For Ve^2 to equal C^2 the mass to distance ratio must equal to 6.734680077 x10^26 kg/meter

Where C=Speed of light
If a neutron star Existed it would need light energy to breakup into protons and electron thus regaining back its original structure. That means a burned out star becomes a space Sponge soaking energy and not reflecting it back.

The Earth is a good analogy,because its also a space sponge which soaks up light and reflect only a small percentage back .The rest is absorbed by the Earth's Atoms raising their temperature..

Answer 3

get away speed is particularly a touch elementary theory. the two an merchandise has sufficient kinetic potential (speed) to be switched over into ability potential (elevation) to flee a planet or it incredibly is going to fall back to earth. Throw a baseball up interior the air and it will return to earth because of the fact it replaced into not initially traveling at approximately seven miles according to 2d (neglecting wind resistance). because of the fact the baseball rises it incredibly is kinetic potential is switched over to ability potential because it slows down (and no potential is misplaced!). of course, a rocket with a almost inexhaustible furnish of potential could desire to upload sufficient potential to preliminary speed to flee. A black hollow is an totally distinctive animal! interior of a black hollow (time horizon) area is so curved that if a photon is thrown up (by a flashlight?) it could desire to have too little preliminary speed (the fee of sunshine) to flee and could return in the direction of the middle of the black hollow the place all count is condensed right into a singularity so dense that it could desire to occupy the era on the top of this sentence(.) The gravitational attraction of such centred mass is super and approachable, while we are constrained to impending the earth's middle of gravity by the earth's floor (to not point out the warmth with intensity). If the earth's mass could desire to be condensed right into a singularity it too could be a black hollow (and invisible in area).

Answer 4

~250000 mph
light ~670000000000 mph
