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 radius of a black hole is the distance from the singularity (center) to. the point where the gravitational field becomes zero. the event horizon, from which light cannot escape. the outside radius of the massive solid body forming the black hole.. The black hole modifies spacetime around it so much that particles and X-rays are created in the vacuum itself, just outside the event horizon. The X-rays are produced by vibrations of the black hole itself, and therefore they come from the event horizon, and not from inside the black hole.
