INGLÉS ESPAÑOL FRANCÉS A satellite of the Earth has a mass of 100 kg and is at a height of 2.0x10 3 km above the earth's surface. Determine the gravitational potential energy of the Earth-satellite system. Enviar com TardadoRick is an Aerospace Engineer at NASA’s Jet Propulsions Laboratory (JPL), and is designing the next mission to Pluto called “New Horizons 2: The Sequel". This time Rick plans to study Pluto's largest moon Charon. Charon has a mass of 1.586 ×1021 kg and a mean radius of 606 km, and might have a nitrogenous atmosphere (N2) just like Pluto. If, for a massive object to have an atmosphere its escape speed must be 12 times greater than the root-mean- square (rms) velocity of the gas (otherwise the gas will slowly leak away over time), what is the maximum temperature that Charon can have and still have a nitrogenous atmosphere? [Charon has a temperature of -281 °C = 55 K, day or night.]The escape velocity from the surface of planet A is 5700 m/s.
