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 6.0×105 km (comparable to our sun); its final radius is 17 km. If the original star rotated once in...

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 10^14 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 7.0×10^5 km (comparable to our sun); its final radius is 18km . If the original star rotated once in...

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...

Neutron stars are extremely dense objects formed from the remnants of supernova explosions. Many rotate very rapidly. Suppose the mass of a certain spherical neutron star is twice the mass of the Sun and its radius is 11.0 km. Determine the greatest possible angular speed it can have so that the matter at the surface of the star on its equator is just held in orbit by the gravitational force. rad/s

1) Neutron stars are extremely dense objects that are formed from the remnants of supernova explosions. Many rotate very rapidly. Suppose the mass of a certain spherical neutron star is twice the mass of the Sun and its radius is 14.0 km. Determine the greatest possible angular speed the neutron star can have so that the matter at its surface on the equator is just held in orbit by the gravitational force. (The mass of the Sun is 1.99 1030...

A neutron star is a star that remains after a supernova, having a large enough density that the it is comprised of mostly neutrons and few protons. A pulsar is a neutron star that spins, radiating electromagnetic energy. We detect this energy as radio waves, noticing that they pulse at a rate of 1 kHz (1000 Hz). Let's assume that this rate corresponds to the rotations per second of the star (1000 rotations per second). Any solid sphere has a...

PartA Constants Suppose a star the size of our Sun, but with mass 9.0 times as great, were rotating at a speed of 1.0 revolution every 10 days. If it were to undergo gravitational collapse to a neutron star of radius 12 km, losing three-quarters of its mass in the process, what would its rotation speed be? Assume also that the thrown-off mass carries off either no angular momentum Express your answer using two significant figures. A2c rev/s Part B...
