Part dyou are conducting an experiment inside a train car that may move along level rail tracks. a load is hung from the ceiling on a string. the load is not swinging, and the string is observed to make a constant angle of 45β with the horizontal. no forces other than tension and gravity are acting on the load. which of the following statements are correct? check all that apply. check all that apply. the train is an inertial frame of reference. the train is not an inertial frame of reference. the train may be instantaneously at rest. the train may be moving at a constant speed in a straight line. the train may be moving at a constant speed in a circle. the train must be speeding up. the train must be slowing down. the train must be accelerating.

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?
