A dual-mode flip-flop has two inputs, M and X. M is the mode input which causes the deviceto operate either as a D flip-flop or T flip-flop. When M is 0, the device behaves like a Dflip-flop with X serving as the D input. When M is 1, the device behaves like a T flip-flopwith X serving as the T input. Design the flip-flop using NAND cell.

Ariver flows from north to south at 8 km/h. a boat is to cross this river from west to east at a speed of 20 km/h (speed of the boat with respect to the earth/ground). at what angle (in degrees) must the boat be pointed upstream such that it will proceed directly across the river (hint: find the speed of the boat with respect to water/river)? a 288 b. 21.8 c. 326 d. 30.2

Steam enters a converging nozzle at 3.0 mpa and 500°c with a at 1.8 mpa. for a nozzle exit area of 32 cm2, determine the exit velocity, mass flow rate, and exit mach number if the nozzle: negligible velocity, and it exits (a) is isentropic (b) has an efficiency of 94 percent
