1.5-kg of water that is initially at 90◦c with a quality of 5 percent occupies a spring-loaded piston-cylinder device. this device is now heated until the pressure rises to 900 kpa and the temperature is 280◦c. determine the total work produced during this process, in kj.

Awheel rotates without friction about a stationary horizontal axis at the center of the wheel. a constant tangential force equal to 82.0 n is applied to the rim of the wheel. the wheel has radius 0.150 m . starting from rest, the wheel has an angular speed of 12.8 rev/s after 3.88 s. what is the moment of inertia of the wheel?

What property is a characteristic of a substance that can be observed and does not change the identity of the substance

Acoyote chasing a rabbit is moving 8.00 m/s due east at one moment and 8.80 m/s due south 4.25 s later. let the x axis point due east and the y axis point due north. find the direction of the coyote's average acceleration during that time.
