Two blocks with masses m1=3.17kg, and m2=7.14kg hang from each other tied to the roof of an elevator, which rises with acceleration pointing upwards, of magnitude a=0.57m/s^2. for this problem, take the positive direction upwards, and use g=9.8m/s^2 as the magnitude of the acceleration due to gravity. obtain t2 in newtons

Refrigerant 134a enters an insulated compressor operating at steady state as saturated vapor at -26°c with a volumetric flow rate of 0.18 m3/s. refrigerant exits at 9 bar, 70°c. changes in kinetic and potential energy from inlet to exit can be ignored. determine the volumetric flow rate at the exit, in m3/s, and the compressor power, in kw.

Burgers vector is generally parallel to the dislocation line. a)-true b)-false
