If only 10 pounds is required to lift a 500-lb block, how much chain must be played out to lift the engine 3.0 inches?

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)

Which equation is mostly likely used to determine the acceleration from a velocity vs time graph

Hurry! how much heat is absorbed by a 72g iron skillet when its temperature rises from 11°c to 23°c?
