If mercury barometer reads 760mm mercury what is the atmosphere pressure on Nm-2 (density of mercury is (1.3×10^4kgm-3)

The slope of a velocity time graph over any interval of time gives the during that interval

Ryan is examining the energy of the particles in a bar of gold. what is ryan most likely studying?

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)
