What is the minimum mass of a neutron star? - Physics Forums
2018年1月23日 · The minimum mass of a neutron star is approximately 1.4 times the mass of our sun, or 2.8 x 10^30 kilograms. This is known as the Chandrasekhar limit, and it is the point at which the gravitational force of the star overcomes the electron degeneracy pressure, causing the star to collapse into a neutron star.
Velocity and kinetic energy of a neutron - Physics Forums
2008年8月20日 · The velocity of a neutron can be calculated using the formula v = √(2E/m), where v is the velocity, E is the kinetic energy, and m is the mass of the neutron. This formula is derived from the kinetic energy equation, KE = 1/2mv².
Why can't a neutron be thought of as a proton plus an electron …
2003年9月17日 · In elementary physics, it is said that the neutron can "sorta" be thought of as a proton plus an electron together. The mass of the neutron is slightly higher than a proton, by approximately the mass of an electron; in beta decay, a neutron decays into a proton, electron and neutrino; the neutron is neutral, since the two charges cancel.
What is the Maximum Mass of a Neutron Star? - Physics Forums
2021年11月5日 · The maximum mass of a neutron star is estimated to be around 2-3 times the mass of our sun, or approximately 2x10^30 kilograms. How is the maximum mass of a neutron star determined? The maximum mass of a neutron star is determined by the balance between the inward pull of gravity and the outward pressure from the neutron degeneracy, which is ...
Specifically, why is the neutron heavier than the proton? - Physics …
2018年7月25日 · These experiments consistently show that the neutron is slightly heavier than the proton. Are there any other factors that contribute to the neutron's heavier mass? Yes, there are other factors that contribute to the neutron's heavier mass, such as the internal energy of the particles and the mass difference between the "up" and "down" quarks.
Elastic collision neutron problem - Physics Forums
2009年9月9日 · A neutron has an elastic collision with a stationary deuteron. Mass of neutron is 1 amu, mass of deuteron is 2 amu. the neutron is deflected through 90 degree angle. Prove that the neutron loses 2/3 of it's initial kinetic energy to the deuteron. Homework Equations I'm guessing the conservation of momentum and kinetic energy equations
Neutron star mass-radius relation plot - Physics Forums
2017年7月8日 · The mass is usually measured in terms of the solar mass (M☉) and the radius in kilometers (km). This is because the mass of a neutron star is typically several times that of the sun, and their radii are much smaller than a kilometer. What is the maximum mass that a neutron star can have? The maximum mass that a neutron star can have is called ...
Calculating the Rest Mass Energy of One Mole of Neutrons
2009年3月9日 · The rest mass energy of a neutron is approximately 939.57 MeV (mega electron volts), which is equivalent to 1.67493 x 10^-27 kilograms. How is the rest mass energy of a neutron calculated? The rest mass energy of a neutron is calculated using Einstein's famous equation E=mc^2, where E represents energy, m represents mass, and c represents the ...
Neutron Star Mass: Understanding the Chandrasekhar Limit
2008年1月18日 · Can the mass of a neutron star change? Yes, the mass of a neutron star can change over time. It can accrete matter from a companion star, which can increase its mass. It can also lose mass through various processes, such as emitting high-energy radiation or merging with another neutron star. However, the mass of a neutron star will always ...
Is it possible to calculate the difference in mass between a Proton …
2010年11月16日 · The mass of a Proton is approximately 1.0073 amu, while the mass of a Neutron is approximately 1.0087 amu. By subtracting the mass of a Proton from the mass of a Neutron, we can calculate the difference in mass between the two particles, which is approximately 0.0014 amu.
