Consider a jet on the deck of an aircraft carrier. In order to take off, a catapult is attached to the jet and it is flung off the deck. An F-18 has a gross weight of approximately 17,000 kg and must reach speeds of about 270 km/hr by the end of the 150 m deck. The catapults on aircraft carriers must be able to launch a variety of aircraft that have different masses and minimum air speeds for flight! How would you ensure that you provide enough energy to the aircraft to get it safely off the deck of the aircraft carrier?

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?
