The initial conditions for an air-standard Otto cycle operating with a compression ratio of 8:1 are 95 kPa and 17o C. At the beginning of the compression stroke, the cylinder volume is 2.20 L ( 1 L=0.001 m3)and 3.60 kJ of heat is added during the constant volume heating process. Calculate the pressure and temperature at end of each process of the cycle, and determine the thermal efficiency and mean effective pressure of the cycle.
Photoelectric effect An effect described by A. Einstein that demonstrates that light appears to be built up of photons or particles. Light can do excite electrons (called phot
The mass of a proton and of an antiproton is 1.00728 u. Recall that the conversion of exactly 1 u into energy yields 931.5 MeV. a. Measure the mass used up when a proton and
