Air at 80 kpa and 127°c enters an adiabatic diffuser steadily at a rate of 6000 kg/h and leaves at 100 kpa. the velocity of the airstream is decreased from 230 to 30 m/s as it passes through the diffuser. find (a) the exit temperature of the air and (b) the exit area of the diffuser.

As a pendulum bob swings back and forth several times, the maximum height it reaches becomes less and less. this is because more and more of the pendulum bob's energy is being transformed into a. heat energy b. kinetic energy c. potential energy d. kinetic energy and potential energy

Arocket starts from rest and moves upward from the surface of the earth. for the first 10.0 s of its motion, the vertical acceleration of the rocket is given by ay = 12.80 m/s32t, where the +y-direction is upward. (a) what is the height of the rocket above the surface of the earth at t = 10.0 s? b) what is the speed of the rocket when it is 325 m above the surface of the earth?
