Choose...
Jupiter has a mass of 1.9×10^27 kg, a radius of 7.1×10^4 km and one day lasts 9 hours and 55 minutes. How many times is the force of gravity bigger on Jupiters equator comared to Earth?
A synchronous satellite, which always remains above the same point on a planet's equator, is put in orbit around Jupiter so that scientists can study a surface feature. Jupiter rotates
every 9.84 h. Use the data of Table 13.2 to find the altitude of the satellite.
