Rewrite the printreverse() method so that it uses iteration. this method is easy to implement using recursion–as we have done in stringnode. java–but it’s more difficult to implement using iteration. here are two possible iterative approaches, either of which will receive full credit:

A)-in the process of engineering design, explain the contribution of material selection. b)- explain the procedure of synthesis as is employed in engineering design. c)- is there any relationship between ergonomics and engineering design? explain. d)- safety consideration in engineering design includes human, product and the enviroment . explain how safety will be incorporated into the design?

The process in which the system pressure remain constant is called a)-isobaric b)-isochoric c)-isolated d)-isothermal

An ammonia compressor has a 5% clearance volume and displacement rate of 80 l/s and pumps against a condensing temperature of 40°c. for two different temperatures of -10°c and 10°c, compute the mass flow rate of refrigerant assuming the clearance volumetric efficiency applies. discharge specific volume corresponding to-10°c and 10°c are 112.5 l/kg and 95 l/kg, respectively.
