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.
Event horizon a.k.a. Schwarzschild radius. The point of no return. First theorized by John Michel in 1784. Starting from the escape velocity formula, derive an equation for the radius of the event horizon in terms of m (the mass of the black hole), g (the gravitational constant), and c (the speed of light).
