After a supernova what compels the left over core to be either a neutron star or a pulsar? is it decided before or after explosion? any thoughts would be appreciated.

okay, then i can probably assume that there is nothing known as wave factor. thanks for the help!

somebody asked me earlier

Please can someone gives its definition or explain what it means?? I have searched everywhere but without luck. thanks a lot.

Hello! Thanks a bunch, it really helped.

You can take P = h X surface density X g

Hello! thanks for the information. could you please suggest me a book or some other resource regarding this? I need more. many thanks!

Hell all! thanks for the comments, really helped. The problem is much more harder than I imagined. Can someone help me start it, please ?? I have the basic momentum conservation equation but not sure how that will help. h/λ1 + 0 = h/λ2 + mev (1) the photoelectic equation is...

Ok, sorry. then for a photon at rest p = m0c from the relation E2 = p2c2 + m02c4 here E = 0, if its at rest, will it?

Hello! As the title suggests I tried to use the photoelectric equation and convert it into conservation of momentum equation but something's not fitting in. We know that the initial momentum of the electron and the final momentum of the photon would be zero. Is there any other way...

thanks! got the answer!

Homework Statement Hello! The question is as follows: 1. You are provided with a 1 cm3 of biological sample from which 0.1 mm thin sections are cut. A search for virus cells at a magnification of 100,000 has been proposed. The fluorescent screen on which the image is to be projected...

thank you very much.
