The Schwarzschild radius, or event horizon, of a black hole is the distance from a black hole at which the escape velocity is the speed of light. Calculate the Schwarzschild radius of a black hole with the mass of Mount Rushmore (reminder: Mt. Rushmore has a mass of about 3 x 1013 grams).

Schwarzschild radius (sometimes referred to as the gravitational radius) is the distance from the center of an object such that, if all the mass of the object were compressed within a sphere of such radius, the escape speed from the surface would equal the speed of light. It, thus, defines a spherical boundary called the event horizon, commonly associated with black holes, beyond which the events cannot affect an outside observer. Theoretically, any amount of matter will become a black...

Black hole of Schwarzschild.
The Schwarzschild solution is an exact solution of Einstein's
equations in the vacuum that is static and spherically
symmetric.
The interval is given by: (1)
(a) they are conserved quantities: (2)
Due to an additional symmetry, the movement is confined to a plane,
which can be chosen as the equatorial plane, θ = π / 2. Write (1)
in terms of,A (r), (dr / dτ) 2 and dτ.
(b) Show that (3) is constant throughout
geodesics....

3. In this problem, we are going to examine the supermassive black hole in the center of our galaxy, Sagittarius A.. (a) (15 points) We can calculate its mass using the orbits of stars gravitationally bound to it in the same way that you can use the Earth's orbit to calculate the mass of the Sun). The orbit of a star, S2, has been fully mapped out. Its period is 15.24 yr and semi-major axis length is 980 AU. Using...

In a newly discovered exoplanetary system one planet orbits its star in 56 days with an average orbital radius of 107,588,122 kilometers. It is observed that another planet in the same system has orbital period of 373 days. What is its average orbital radius of the second planet? Express your answer in kilometers, use scientific notation and round the coefficient to two decimals. In a newly discovered exoplanetary system one planet orbits its star in 57 days with an average...

3-axis center of mass FIGURE 8.24 Problem 20: (Tippe top) This simple device appears to defy the laws of classical mechanics. Start it spinning, and it eventually inverts, raising its center of mass to a higher position, where it spins happily until it runs down. We will examine this strange behavior qualitatively here. The top has a mass M and radius R. The center of mass is a distance a from the center of the sphere as shown in Figure...

3. Laser light of wavelength 2 is incident on a mask containing two very narrow slits. A screen is placed beyond the mask. The photograph shows the pattem of bright spots (shown in white) and dark spots (shown in black) that appears near the center of the screen. Point D in the center is the brightest. (a) If the wavelength of the light is decreased, would...
