Neutron stars are stars that have collapsed under the influence of the gravitational force into what are essentially enonnous nuclei composed mostly of neutrons. Why do these neutrons not decay? Please write the full answer
Homework Answers
Neutrons in atomic nuclei are very stable, but free neutrons outside a nucleus will decay in a proton and electron (and technically a neutrino) in about 15 minutes through beta decay. ... Now the force holding the star together against gravity is the neutron degeneracy pressure .Apparently, this is extra pressure due to gravity in contrast to "negative pressure" of proton Coulomb repulsion in a nucleus keeps neutron star from decaying .

Two particles moving under the influence of their mutual gravitational force describe circular orbits about one another with period r. a. Use Newton's second law to find an expression for ro, the radius of the particles' orbit around each other in terms of r b. Write an expression for the total energy of the system. (You don't have to use your answer to part a; keep it as ro.) c. Both particles are pushed inward such that their separation is...

egatively defined objects: Summarize the best observational evidence that astronomers have for the existence of stellar-mass black holes. Contrast this with the observational evidence that pulsars exist. Do you agree or disagree with the statement that the best evidence for stellar-mass black holes is that scientists have detected objects for which an alternate explanation is lacking? How does your answer influence your confidence in the existence of black holes? Does the strong observational confirmation of Einstein's general theory of relativity...

Does the force of gravity
alone provide the means for the centripetal force, is this why they
are equal ? For explaining why there is no normal force, could you
see it as the astronaut having the same acceleration as the ship
and so the relative acceleration = 0, so it's under the illusion
almost of having no acceleration so there's no force ? Please !! If
you have different reasoning please share. I'm just trying to wrap
my head...

The discovery of pulsars –rotating neutron stars that generate regular pulses of radiation at their spin rate- was fortuitous. A group of astrophysicists from Cambridge University lead by Anthony Hewish was looking for quasars (these are extremely bright, compact and remote objects that emit up to a thousand times as much light as our entire galaxy). For that purpose the research group designed a radio-telescope that was built on the flat fields surrounding Cambridge in central England. This telescope did...

You have been able to get a part-time job in a University study the forces between nuclei in order to understand the energy output of the Sun. To do this experiment, you shoot alpha particles from a Van de Graaf accelerator at a sheet of lead. The alpha particle is the nucleus of a helium atom and laboratory. The group is planning a set of experiments to is made of 2...
