An earth-orbiting satellite has an elliptic orbit with a semimajor axis of 1.05 du where 1 du is equal to 1 earth radius. when the satellite is at the end of the semi-minor axis, it receives an impulsive velocity change (a fuel burn) just sufficient to place it on a parabolic escape trajectory. what is the magnitude of the velocity change? compute the answer indu/tu and then convert to km/s. an earth-orbiting satellite has an elliptic orbit with a semimajor axis of 1.05 du where 1 du is equal to 1 earth radius. when the satellite is at the end of the semi-minor axis, it receives an impulsive velocity change (a fuel burn) just sufficient to place it on a parabolic escape trajectory. what is the magnitude of the velocity change? compute the answer indu/tu and then convert to km/s.

Acylinder with a movable piston contains 11.7 moles of a monatomic ideal gas at a pressure of 1.32×10^5 pa. the gas is initially at a temperature of 300 k. an electric heater adds 43200 j of energy into the gas while the piston moves in such a way that the pressure remains constant. cp=20.79 j k^−1 mol^−1 for a monatomic ideal gas, and that the number of gas molecules is equal to avogadro's number (6.022×10^23) times the number of moles of the gas. (a) what is the temperature of the gas after the energy is added? (b) what is the change in volume of the gas? (c) how much work is done by the gas during this process?
