1 kg of water that is initially 90oC with a quality of 10 percent occupies a spring-loaded piston-cylinder device. At this state, a linear spring is touching the piston and exerting no force on it. The device is now heated to compress the spring until the pressure rises to 800 kPa and the temperature is 250oC. Determine the total work produced during this process, in kJ.

Ajet plane has a sound level of 120 db at a distance of 60 m. what is the q23. sound level at a distance of 6.0 km? (60)2 (6000)? om solution 80db db, hint: 16x assume ultrasound waves travel through the body of an animal at 1540 q24. m/s. if a 30,000 hz signal were reflected off a portion of a heart which was moving toward the source at 3 m/s, what frequency signal would return to the stationary source? solution 30.117hz
