    Umm.. we just need to know that a H+ is transferred from the acid part to the the alcohol part...

    Umm.. we just need to know that a H+ is transferred from the acid part to the the alcohol part and this means it becomes bipolar in nature. Further this gives it two important proerties: Solubility and High melting and boiling points. Thats all I guess :) Sre u doing Physics 5 tomorrow btw?

    Binding energy is the energy released when a nucleus is split into individual protons and neutrons. the graph will be like this with a peak at Iron Calculate the binding energy per nucleon for both. 16O its 123.45/16 = 7.72 and 17O its 126.43/17 = 7.44. Since more energy is holding O-16...

    I mean we compare the angle with a star that appears "fixed" from the earth. (a very far star basically) ohh! Imma solve all the questions but just quickly... not full solutions...

    It 'appears' more luminous but it isnt. Thats exactly what ís the reason for it being far away. ahan! I did the Study Guide and now the papers... n i think its cuz of exam pressure... >.<" Its hard to do stuff when ur tensed n nervous :(

    No problem :D B is as luminous as A according to the question, but from the earth it seems less brighter. That can only happen if B is far. LIke if u have something far it seems less bright than if it were near :) How much are u done with? I'm doing Past papers now :)

    Welcome n sure ... Red Giants are stars with a large surface and cooler. They have moved off the main sequence. Parallax displacement is the apparent change in angle of a star when viewed from the earth six months apart compared to a distant fixed star. 5 days (1 wave) B is more luminous...

    Its perfectly okay with me :D Dont feel so, I'm learning a lot myself :) Q87 I dunno what formula they are using :eek: I used a = v^2/r but I'm not getting the answer :S @87 which part? Dont apologize please :) I'm sorry for my late responses btw :oops:

    We recieve a range of wavelengths from the galaxy acctually (remeber the bell-shaped curve for Wien's displacement Law?) and its not nessecary that it's ALWAYS the peak one, all the wavelengths will show the same shift.
