Currently, astronomers are observing the universe across many different regions of the electromagnetic spectrum, from gamma rays to radio waves. one of the primary issues when considering communication with potential life outside our planet is how an extraterrestrial signal would be distinguished from natural radiation sources. sort the following source properties by whether they might be considered as originating from intelligence or simply be natural phenomena: 1) constant, unchanging signal2) random radio fluctuations3) sequence of pulses varying over time4) single strong visible light burst that fades away over months5) identical repetitive pulses

Atwo-stage air compressor operates at steady state, compression 10m^3/min of air from 100 kpa and 300k to 1200 kpa. an intercooler between the two stages cools the air to 300k at a constant pressure of 350 kpa. the compression processes are isentropic. a) calculate the power required to run the compressor, in kw b) compare the result to the power required for isentropic compression from the same inlet state to the same final pressure.
