You are in space watching the two astronauts at rest in your frame of reference. They have identical mass, connected by a 12-m long cable, holding a heavy canister giving the center of mass to be two meters from Astronaut X. Astronaut X throws the canister to Y who catches it. How far will Astronaut move from his original position?​

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)
