What is a quark star?
A quark star is a hypothetical star that forms when a star that is too big to form a neutron star but less than a black hole collapses the neutrons slightly into their component particles.
What are neutral pions made of?
Neutral pions are composed of a quark-antiquark pair, specifically an up quark and an anti-up quark or a down quark and an anti-down quark. They are the lightest mesons and are unstable, decaying rapidly into two photons.
What is an anti-down quark?
An anti-down quark is the antimatter counterpart of a down quark, one of the elementary particles that make up protons and neutrons in the atomic nucleus. It has opposite electric charge to a down quark and can combine with other quarks to form antimatter particles.
What are 3 particle's of the atom?
The up quark, the down quark, and the electron. Two up quarks and a down quark form a proton, and two down quarks and an up quark form a neutron.
What is the name of Quark's bar in Star Trek?
Quarks's
What is is the Relationship between quark and subatomic particle?
A quark is a kind of subatomic particle, and 3 quarks makes up another subatomic particle (a baryon). A quark and an anti-quark make up another kind of sub-atomic particle, (a meson).
What particles are released from the nucleus when a down quark changes into an up quark?
When a down quark changes into an up quark in the nucleus, a Nestor is changing into a proton. The particles released (for almost all neutron to proton transformations) are an electron and an electron anti-neutrino.
Why do protons and electrons combine to form neutrons in a neutron star if protons are made of two up quarks and a down quark electrons aren't made of quarks and neutrons are made of two down quarks a?
Actually 'an' up quark.The weak nuclear force permits an interaction between an up quark and an electron that converts the up quark to a down quark and the electron ceases to exist, also an interaction between a down quark and a positron that converts the down quark to an up quark and the positron ceases to exist. There are also weak nuclear force interactions that change quark types by emitting electrons or positrons. Both the absorption and emission interactions described above are referred to as Beta Decay Processes. All Beta Decay Processes also involve emission of an electron neutrino or an electron antineutrino (the lightest known particle having a nonzero mass and a particle that has almost no interaction at all with other matter).
Two up quarks and one down quark make up which of the following particles?
Yes, contrast to Proton which is made up of Two up and one down quark.
What is an up quark?
The up quark is one of the two most stable types of quarks in the universe. It is one seen very often. For instance, a proton is composed of two up quarks and a down quark. It has a charge of +2/3.
What is the difference between a quark and a quasar?
Magnitude - sheer size.A quark is tiny - it takes 3 to make a single proton.A quasar is a "quasi star" and is actually an entire galaxy with its core on fire(not actual fire with flames, but in the act of constantly blowing up).
Is quark bigger or neutron?
Neutron is bigger than a quark. A neutron is a composite particle made up of three quarks, while a quark is a fundamental particle that makes up protons and neutrons.
