The weight (in pounds) w t(d) of an object varies inversely as the square of its distance (in thousands of miles) d from the center of Earth a. An astronaut weighs 180 pounds at sea level (about...
The gravitational force F between an object and the Earth is inversely proportional to the astronaut weighs 206 pounds on the surface of the Earth, what will his astronaut weigh 400 miles above the Earth? Assumethat the radius of the Earth s400mles (Round off your answer to the nearest pound. square of the distance from the object to the ceriter of the Earth. If an How to enter your answer Ib The gravitational force F between an object and the...
Please Help: Average air pressure at sea level is about 14.7 pounds per square inch, and Earth's total surface area is about 197,000,000 square miles. One square mile equals 4,000,000,000 square inches. Using this information, how much does the entire atmosphere weigh? Show your work for full credit, and either use scientific notation OR group digits in your answers with commas (e.g. 100,000,000 instead of 100000000).
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...
