Determine whether the geometric series is convergent or divergent. (5 − 7 + 49 5 − 343 25 + ) convergent divergent correct: your answer is correct. if it is convergent, find its sum. (if the quantity diverges, enter diverges.) $$ correct: your answer is correct.

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

The higher the astm grain size number, the finer the gran is. a)-true b)-false

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
