Ou wish to pilot a small boat across to a buoy which is anchored to the bottom of the bay. There is a current that flows at the angle θ = 28.5 shown at 3.0 m/s. The boat starts out directly across from the buoy, a distance d of 370.0 m away. You choose to steer your boat straight across, aiming the front of the boat in the +y-direction. You notice that the boat's speedometer reads 6.0 m/s. The boat ends up to the right of the buoy at the point shown.

The temperature of air decreases as it is compressed by an adiabatic compressor. a)- true b)- false

Water vapor initially at 10 bar and 400 °c is contained within a piston-cylinder assembly. the water lost heat to the surrounding according to isochoric (iso-volumetric) process until its temperature is 150 °c. the water is then condensed isothermally to saturated liquid. for the water as a system, calculate the work in kj/kg
