Find the speed necessary for the given circular orbit around Earth. Let GM = 9.56×10^4 cubic miles per second
per second, and assume the radius of Earth is 4000 miles.
The orbit of a communications satellite r miles above the
surface of Earth that is in geosynchronous orbit. [The satellite
completes one orbit per sidereal day (approximately 23 hours,
56 minutes), and therefore appears to remain stationary above
a point on Earth.]

On the way home from visiting his family, vincent’s plane cruised at an altitude of 3.2 × 10^4 feet. he had heard that a man named felix baumgartner skydived from an altitude of 1.28 × 10^5 feet. vincent wants to know how much higher felix went on his skydiving trip. question 1 you have already seen how adding numbers works in either scientific notation or standard notation. but can you subtract numbers in scientific notation and get the same results as subtracting in standard notation? to find out, first solve vincent’s problem in standard notation. part a write the cruising altitude of vincent’s plane in standard notation.
