A2.00 kg block is held in equilibrium on an incline of
angle60 degrees by a horizontal force f. if
thecoefficient of static friction between the block and inline
isms= .300 determine the minimum value of
fand the normal force of the incline on the
block.

Arigid tank is divided into two equal parts by a partition. one part of the tank contains 3 kg of compressed liquid water at 400 kpa and 60°c while the other part is evacuated. the partition is now removed, and the water expands to fill the entire tank. determine the entropy change of water during this process, if the final pressure in the tank is 40 kpa. use steam tables.
