Physics Question Answers & Calculations

The strong interaction is observable at two ranges and mediated by two force carriers. On a larger scale (about 1 to 3  fm ), it is the force (carried by  mesons ) that binds  protons  and  neutrons  (nucleons) together to form the  nucleus  of an  atom . On the smaller scale (less than about 0.8 fm, the radius of a nucleon), it is the force (carried by  gluons ) that holds  quarks  together to form protons, neutrons, and other  hadron  particles.  In  the latter context, it is often known as the  color force . The strong force inherently has such a high strength that hadrons bound by the strong force can  produce new massive particles . Thus, if hadrons are struck by high-energy particles, they give rise to new hadrons instead of emitting freely moving radiation ( gluons ). This property of the strong force is called  color confinement , and it prevents the free "emission" of the strong ...

Hadrons are composite particles made of two or more quarks sometime there are also anti-quarks in them. They are held together by strong force Source:- https://en.m.wikipedia.org/wiki/Hadron

Answer: - The photosphere is a star's outer shell from which light is radiated.

Answer: - A convection zone, convective zone or convective region of a star is a layer which is unstable to convection. Energy is primarily or partially transported by convection in such a region. In a radiation zone, energy is transported by radiation and conduction

Answer: - Convection is the heat transfer due to the bulk movement of molecules within fluids such as gases and liquids, including molten rock

Answer: - A radiation zone, or radiative region is a layer of a star's interior where energy is primarily transported toward the exterior by means of radiative diffusion and thermal conduction, rather than by convection. Energy travels through the radiation zone in the form of electromagnetic radiation as photons.
