Task: using only binary fas to perform the actual addition, design a circuit that performs as an octal fa . more specifically, this circuit would input the two octal digits a, b, convert them into binary numbers, add them using only binary fas, convert the binary result back to octal, and output the sum as an octal digit, and the binary carry out.

The mass flow rate of the fluid remains constant in all steady flow process. a)- true b)- false

Acompressor receives the shaft work to decrease the pressure of the fluid. a)- true b)- false

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
