Draw a synchronous decade counter, using J K flip-flops like the one below. As well as the flip-flops you can use as many AND, OR, NAND, NOT, etc. gates as you need. Note there are no asynchronous set or reset inputs so you need to use logic to count and reset. What is the modulus and how many flip-flops are needed?

Fluids at rest possess no flow energy. a)- true b)- false

Apiston-cylinder device contains 0.1 m3 of liquid water and 0.9 m3 of water vapor in equilibrium at 800 kpa. heat is transferred at constant pressure until the temperature of water reaches 350 °c. determine (a) the quality of water at the initial state (b) the work associated with this process, (c) the heat associated with this process.

Air inially occupying a volume of 1 m2 at 100 kpa, 27 c undergoes three internally reversible processes in series. process 1-2 compression to 500 kpa during which pv constant process 2-3 adiabatic expanslon to 100 kpa process 3-1: constant-pressure expansion to 100 kpa (a) calculate the change of entropy for each of the three processes. (b) calculate the heat and work involved in each process. (c) is this cycle a power cycle or refrigeration cycle?
