How have the competing explanations' experiments on atoms affected the development of the atomic model? A.) The atomic model better represents the actual functioning of an atom.

B.) The atomic model has become much simpler than it used to be.

C.) The atomic model now involves fewer subatomic particles.

D.) The atomic model has become less strong over time.

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)
