A "pulsar" is a rapidly-rotating neutron star, with a core of collapsed matter. The pulsar rotates because the original star rotated.
If\\ WHEN a massive star becomes a supernova, the force of the explosion will crush the core of the star into either a neutron star or a black hole, if the original star was massive enough. The angular momentum (the "spin energy") of the original star doesn't disappear; like a figure skater pulling in her arms to spin faster, the neutron star will spin more rapidly because it has collapsed in size. If the neutron star's axis is pointed somewhere close to Earth, we detect the pulsating x-rays and we call it a "pulsar".
So to answer the question, all supernova remnants contain either neutron stars or black holes, but they are pulsars only if they spin rapidly.
dont know get a book.
Carbon, Hydrogen, and Oxygen proteins contain Nitrogen fats dont
onion cells dont contain chloroplasts as they are underground so cant photosynthesise
No, bacterial cells do not contain nuclei. Bacterial cells are prokaryotic, which means they do not have a membrane-bound nucleus. Instead, their genetic material is present in a circular chromosome located in the nucleoid region of the cell.
they are known as isotopes. Dont ask people to do your homework
i dont know
Pulsars are rapidly rotating neutron stars that emit beams of radiation along their magnetic poles. As these beams sweep across Earth, they create a pulsating signal that can be detected by telescopes. This emission of energy in pulses is what gives pulsars their name.
many stars die as a supernova. not really able to determine which types, because they die at random, but if they dont die as supernovas, they just collapse and disappear into one point in the sky.
No they dont
No. they dont
I dont no !
we dont have pepsi new product. livewire,supernova,revolution wildberry&raspberry why these product not in stores
Almost all foods contain rat poop and they dont contain much. The farmers or producers have no way of changing that because rats are everywhere! It is harmless so dont worry!
i dont know. . . but maybe check it in GoogleNo, but it does contain alcohol.
i really dont know
i dont no im asking u not ur asking me !:s
No... I dont...
