Write a hypothesis for Part I of the lab, which is about the effect on an object being carried by a car, when the car experiences a sudden impact. Use the format of "if . . . then . . . because . . . ” and be sure to answer the lesson question "How can Newton's laws be experimentally verified?” specific to Newton’s first law.

Air enters a gas turbine with two stages of compression and two stages of expansion at 100 kpa and 17°c. this system uses a regenerator as well as reheating and intercooling – the intercooler returns the air to the inlet temperature. the pressure ratio across each compressor is 4 ; 300 kj/kg of heat are added to the air in each combustion chamber; and the regenerator operates perfectly while increasing the temperature of the cold air by 20°c. determine the system’s thermal efficiency. assume isentropic operations for all compressor and the turbine stages and use constant specific heats at room temperature.
