comment Is it possible for a sound to be louder as you move away from it?
I often hear whistles of trains at night in winter though I can't hear it in Summer. I am used to think that my location is such that I am getting the sound in a similar fashion as in total internal reflection of light in air in the case of mirage in a desert. You may google it whether it may be possible in this way or not. But I am not sure.

comment How is gravity consistent when you split an object into multiple pieces?
,I think you should review your answer and originally should integrate in the same way as proposed by Robin Ekman as it seems your final answer is not correct.

comment Why is an electron still an elementary particle after absorbing / emitting a photon?
@Ross Millikan, I think Asker wants to know when two elementary particles assemble why do we get still an elementary particle instead of a composite particle.So the answer should be more on "why" part.

comment binding energy of a nucleus is positive?
Though my original question is resolved from the two answers. But I am not able to apply the same concept that you have told in the case of quarks forming a proton or neutron. m(u)=2.3 MeV , m(d)=4.8 MeV , then how come mass of protron is 931 MeV if you want to bring analogy with "nucleons forming nucleus"?

comment why do we get continuous intensity in spectra?
I am not taking about Heisenberg uncertainty principle. The finite width of each band is okay with me. But why doesn't the tail go to zero?? For example let's take the fig as example. In the blue trace at about 1450 (1/cm) we can see a peak and again at 1300(1/cm) we see another peak. In between them how are we getting that much intensity even though we don't have any state there.
