Acylinder with a movable piston contains 11.7 moles of a monatomic ideal gas at a pressure of 1.32Γ10^5 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^β1 mol^β1 for a monatomic ideal gas, and that the number of gas molecules is equal to avogadro's number (6.022Γ10^23) 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?

Aboat radioed a distress call to a coast guard station. at the time of the call, a vector a from the station to the boat had a magnitude of 45.0 km and was directed 15.0Β° east of north. a vector from the station to the point where the boat was later found is = 30.0 km, 15.0Β° north of east. what are the components of the vector from the point where the distress call was made to point where the boat was found? in other words, what are the components of vector c = b - a?
