Assume Earth to be a uniform, solid, rotating sphere in a completely isolated system.

a) Calculate the size of the radius to which Earth would need to be crushed for it to form a black hole according the the Schwarzchild radius equation.

b) Once the Earth is collapsed into a black hole, what is its angular velocity and frequency?

Astronomers detect stars that are rotating extremely rapidly, known as neutron stars. A neutron star is believed to form from the inner core of a larder star that collapsed, under its own gravitation, to a star of very small radius and very high density. Before collapse, suppose the ore of such a star is the size of our Sun (R = 7105km)with mass 2.0 times as great as the Sun, and is rotating at a frequency of 1.0 revolution every...

Assume a planet (Earth for example) is an uniform sphere of radius R and it has a narrow radial tunnel through its center. Assume that we can position an object anywhere along this tunnel or outside the planet (again Earth as an example). Let Fr equal magnitude of the gravitational force on the object that is traveling through the center of the planet. When the object is found at the planet’s surface, how far from the surface is there a...

A uniform solid disk is mounted on an axle n such a way that it is free to rotate about a horizontal axis. The radius of the disk is 0.450 m and its mass is 27.0 kg. As shown in the diagram, two forces F1 = 84.0 N and F2 = 130 N applied to the disk sets the disk rotating with a constant angular acceleration. Assume the axle is frictionless (a) Calculate the magnitude and direction of the net...

A horizontal turntable is made from a uniform solid disk and is initially rotating with angular velocity of 7.1 rad/s about a fixed vertical axis through its center. The turntable has a radius of 0.23 m and a moment of inertia of 0.04761 kg m2 about the rotation axis. A piece of clay, initially at rest, is dropped onto the turntable and sticks to it at a distance d= 0.16 m from its center as shown in the figure. The...

The mass of the Earth is 5.9737076×1024 kg and its average radius is 6,371,912 m. Assume that all of the world's ice is at the poles and does not contribute to the Earth's moment of inertia when in ice form. (Note that some values were changed to make the problem more interesting.) a) Assuming that the Earth is a perfect solid sphere, what is its moment of inertia? b) If the Earth has a period of 23.93447232 hours, what is...
