Suppose an intelligent society capable of receiving and transmitting radio signals lives on a planet orbiting zagnut, a star 116 light-years away from earth. if a signal were sent toward zagnut in 1999, what is the earliest year that earth could expect to receive a return message? (hint: a light-year is the distance a ray of light travels in one year.)

Agas initially at p1 = 1 bar and occupying a volume of 0.5 liter is compressed within a piston–cylinder assembly to a final pressure p2 = 4 bar. (a) if the relationship between pressure and volume during the compression is pv = constant, determine the volume, in liters, at a pressure of 3 bar. (b) repeat for a linear pressure–volume relationship between the same end states. reference
