Deena made a chart to summarize features of a velocity vs. time graph for objects with constant acceleration and objects with constant velocity. which best describes deena’s error? - the line for constant velocity is not horizontal; it is diagonal and slopes downward. - include the area of the rectangle under the line to find displacement for constant acceleration. - find acceleration by finding the area of the rectangle above the line. - find velocity by calculating the slope of the line. its urgent!

An ideal otto cycle has a compression ratio of 8. at the beginning of the compression process, air is at 95 kpa and 27°c, and 750 kj/kg of heat is transferred to air during the constant-volume heat-addition process. assuming constant specific heats at room temperature, determine (a) the pressure and temperature at the end of the heat-addition process, (b) the net work output, (c) the thermal efficiency, and (d) the mean effective pressure for the cycle. (4390 kpa, 1730 k; 423 kj/kg; 56.4%; 534 kpa)
