For instance, if your health plan has an 80/20 co-insurance rate, (coinsurance rates of 70/30 90/10, and flat rates of $5.00 to $20.00 per doctors office visit are also common) your insurance plan pays for 80% of your eligible medical expenses and youre responsible for the remaining 20%. Zip.
The Schwarzschild radius of an object is proportional to the mass. Accordingly, the Sun has a Schwarzschild radius of approximately 3.0 km (1.9 mi), whereas Earth 's is only about 9.0 mm. The observable universe 's mass has a Schwarzschild radius of approximately 13.7 billion light years.
The Schwarzschild Black Hole. The gravitational field of a Schwarzschild black hole depends on only one constant: a mass. Around this central mass, which is assumed to exist at a single point in space, the gravitational field is isotropic, so it varies only with the distance from the central mass.or a solar mass black hole, the event horizon has a radius of only 3 km. For a one billion solar mass black hole, which is about the maximum mass expected for a black hole at the center of a galaxy, the radius is 20 AU, or about the distance of Uranus from the Sun.
