Show that after all edges are processed by \text{CONNECTED-COMPONENTS}CONNECTE D-COMPONENTS, two vertices are in the same connected component if and only if they are in the same set.

During a steady flow process, the change of energy with respect to time is zero. a)- true b)- false

Draw the engineering stress-strain curve for (a) bcc; (b) fcc metals and mark important points.

An ideal otto cycle with air as the working fluid has a compression ratio of 8. the minimum and maximum temperatures in the cycle are 300 k and 1340 k. use constant specific heats at room temperature to determine (a) the amount of heat transferred to the air during the heat- addition kj/kg, (b) the thermal efficiency, and (c) the thermal efficiency of a carnot cycle ope limits. process, in rating between the same temperature
