Question

which of the properties are true of neutron stars? roughly the size of the earth supported by neutron degeneracy pressure has such strong gravity that light cannot escape mass greater than 1.4 solar masses possible remnant of a type ii supernova

Explanation:

Neutron stars are much smaller than Earth, typically around 20 - 40 km in diameter. They are supported by neutron degeneracy pressure. Black - holes have such strong gravity that light cannot escape, not neutron stars. Their mass is usually greater than 1.4 solar masses (Chandrasekhar limit for white dwarfs). They can be the remnant of a Type II supernova when a massive star collapses.

Answer:

• supported by neutron degeneracy pressure
• mass greater than 1.4 solar masses
• possible remnant of a Type II supernova
