Astar with the mass (m=2.0×1030kg) and size (r=3.5×108m) of our sun rotates once every 30.0 days. after undergoing gravitational collapse, the star forms a pulsar that is observed by astronomers to emit radio pulses every 0.200 s . by treating the neutron star as a solid sphere, deduce its radius.

Explanation:

Using the angular formulas can determine the radius using both values neutron star and the the knowing star so

I=Inertia of the star

w=angular velocity

Notice the angular velocity determinate by the time and the Inertia have the radius value so

the diagram which shows forces as either balanced = same speed or unbalanced = accelerarting

increasing transnational kinetic energy. because the transnational kinetic energy formula consists of only two variables, mass and velocity, increasing one of those properties is the only way to increase an object's transnational kinetic energy. increases to mass and velocity, however, do not have the same impact.
