If a neutron star has a radius of 15 km and rotates 1,382 times a second, what is the speed at which a point on the surface at the neutron star's equator is moving? Express your answer as a fraction of the speed of light. (Note: The speed of light is 3 ✕ 105 km/s.)

Please solve for Tf and how
fast the neuron star rotate in rotations per seconds.
Formation of a Neutron Star A star rotates with a period of 29 days about an axis through its center. The period is the time interval required for a point on the star's equator to make one complete revolution around the axis of rotation. After the star undergoes a supernova explosion, the stellar core, which had a radlus of 1.5 x 104 km, collapses into...
Under some circumstances, a star can collapse into an extremely dense object made mostly of neutrons and called a neutron star. The density of a neutron star is roughly 1014 times as great as that of ordinary solid matter. Suppose we represent the star as a uniform, solid, rigid sphere, both before and after the collapse. The star's initial radius was 8.0×105 km (comparable to our sun); its final radius is 17 km . Part A If the original star...

Estimate the pressure in a 1.5 Mʘ neutron star with a radius of 15 km.
Constants Under some circumstances, a star can collapse into an extremely dense object made mostly of neutrons and called a neutron star. The density of a neutron star is roughly 10"4 times as great as that of ordinary solid matter. Suppose we represent the star as a uniform, solid, rigid sphere, both before and after the collapse. The star's initial radius was 9.0x105 km (comparable to our sun); its final radius is 18 km. Part A If the original star...
If a neutron star and a white dwarf has a total mass of 1M. If the white dwarf has a radius of 9 x 106 m and the neutron star has a radius of 11 km. i) Compare the surface gravity of both stars. ii) What is the density of the neutron star? iii) Assuming the neutron star is entirely made up of neutrons, and that the interparticle separation of a gas of density n is l = n-1/3. How...
A neutron star is an extremely dense, rapidly spinning object that results from the collapse of a massive star at the end of its life. A neutron star with 2.3 times the Sun's mass has an essentially uniform density of 4.8× 10^17 kg/m^3. Part A What's its rotational inertia? Assume the star is a solid sphere. Express your answer with the appropriate units. Part B The neutron star's spin rate slowly decreases as a result of torque associated with magnetic...

7. Antares is a star in Scorpius constellation. Its radius is 3.0AU and its mas is about 12 times the mass of the sun. Antares orbital speed is 20.7 km/sec. Eventually after a couple million years Antares will be converted to a neutron star. Its radius will be 4.3*10-5 AU. Find its orbital speed after it becomes neutron star? Find your answer by rpm. Moment of inertia of sphere is = 2/5 MR2 - 8. A rotor disk in...
A neutron star has a radius of 10 km and a mass of 1.4 Solar masses, what is its density and how does this compare to the nuclear density of 2.3 x 1017 kg/m3 (One solar mass is 1.988 x 1030 kg)
The radius of the Earth is 6370. km. (a) Calculate the linear speed at which a point on the Earth's surface at the Equator is moving because of the Earth's rotation. (b) Calculate the linear speed of a point on the Earth's surface in Houston (Latitude = 29.8 degrees North) due to the Earth's rotation and compare with the result at the Equator.
