What is the pressure amplitude at this distance? Use 344 m/s for the speed of sound in air, 1.20 kg/m3 for the density of air, and 1.00×10−12 W/m2 for the reference intensity.

like poles repel so keep pushing north to north and repels funny to see this

measure their densities same density, same sub

when heated, the valance electrons increased their speed and transferred the heat from electron to electron.   i just took the test.

first thing first of the answer is with technology. second thing second thing is that the big bang theory did not happened u see they say it did but what they dont realize is that like dinasures are still a round they might deny it but they and look at these 12 foot human skelteons they find lets see didnt the bible say something about giants. hope this peace.
