During most of its lifetime, a star maintains an equilibrium size in
which the inward force of gravity on each atom is balanced by an
outward pressure force due to the heat of the nuclear reactions in
the core. But after all the hydrogen "fuel" is consumed by nuclear
fusion, the pressure force drops and the star undergoes a
gravitational collapse until it becomes a neutron star. In a neutron
star, the electrons and protons of the atoms are squeezed
together by gravity until they fuse into neutrons. Neutron stars
spin very rapidly and emit intense pulses of radio and light waves,
one pulse per rotation. These "pulsing stars" were discovered in
the 1960s and are called pulsars.

You can find the escape velocity by equating the total kinetic and gravitational potential energy to zero E=12mv2esc−GmM/r=0E=12mvesc2−GmM/r=0 vesc=2GM/r−−−−−−√vesc=2GM/r where GG is Newton's constant of gravitation, MM is the mass of the object from which the escape is happening, and rr is its radius. This is physics you have seen in the first part of the course, and you should be able to use it to find an escape velocity from any planet or satellite. For the Earth, for example the escape velocity is about 11.2 km/s, and for the Moon it is 2.38 km/s. A very important point about escape velocity: it does not depend on what is escaping. A spaceship or a molecule must have this velocity or more away from the center of the planet to be free…arrow_forwardI;m not sure how to fix this answer, it will not allow 10^3.arrow_forward
