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.

The heater element of a 120 v toaster is a 5.4 m length of nichrome wire, whose diameter is 0.48 mm. the resistivity of nichrome at the operating temperature of the toaster is 1.3 × 10-6 ω·m. the toaster is operated at a voltage of 120 v. (a) what is the power drawn by the toaster? (b) if the cost of electricity is 12 ¢ per kilowatt-hour, and it takes 2 minutes to toast bread, how much does it cost for toasted bread? (c) when the heater element is at room temperature, is the resistivity in the nichrome wire greater than, less than, or equal to it’s resistivity when at operating temperature? explain.
