A sample of an ideal gas goes through the process. From Ato B, the process is adiabatic; from Bto C, it is isobaric with 345 kJ of energy entering the system by heat; from Cto D, the process is isothermal; and from Dto A, it is isobaric with 371 kJ of energy leaving the system by heat. Determine the difference in internal energy Eint ,B 2 Eint ,A . 1 3 P(atm) 0.09 0.20.4 1.2 A C B D V(m 3 )

time (seconds)

answer: 0 meters/second^2

54 degrees incident angle = reflected angle

angle is from normal turned to line of ray

one "light year" is the distance that light travels, through vacuum, in one julian year.   that's 365.25 days, of 24 hours each.
