Air at 200 kpa and 800k enters an adiabatic nozzle at low velocity (can be considered negligible) and is discharged at a pressure of 90 kpa. if the isentropic efficiency of the nozzle is 90%, determine: [20] a. the exit temperature if the process is isentropic b. the maximum possible exit velocity c. the actual exit temperature d. the actual exit velocity

According to newton’s law of universal gravitation, which statements are true? as we move to higher altitudes, the force of gravity on us decreases. as we move to higher altitudes, the force of gravity on us increases. as we gain mass, the force of gravity on us decreases. as we gain mass, the force of gravity on us increases. as we move faster, the force of gravity on us increases.
