in pearson bok ther is no such info and i don hve the other book

aawwhh! Wait i'll just scan the "scribbling" (notes ) I have on this n give u in a sec, there isnt much

Just gimme like 5 mins okay?

ya sure thnx alot

ya sure thnx alot

No problem
Sorry about the mess though, these r just rough notes, and this is all we need to know about life cycle of stars

no its ok its fine and im so thankful 2 u

Ur so welcome ^_^ Just need prayers thats all

btw, where was this question? Past paper?
(Imma do Astrophysics in a while too i guess so just asking )

bt i hve a que isn't after supernova explosion the black holes appear?

its in the old past papers tht i hve given u

I dont think so... I'll check, gimma a min

its in the old past papers tht i hve given u

oh i see! Thanks

in the old past papers 4 astrophysics Q(33) is such type of graphs recommended 2 us?

Well U dont need to learn the graph but u can be asked to use it... all u need to do is read off a mass and the corresponding radius. Use the radius to find the volume and u can easily calculate density

REALLY apologize for such a late response

no its ok and thnx alot how's phy goin?

no its ok and thnx alot how's phy goin?

M glad N no problem at all
Physics? Well its better than bio at least.... Hows urs comming along? Hardly any time now...

mine is medium and ya time is short

IKR
What are u planning to do today? I think I'll finish a bit of bio n den stick to Astrophysics again

ya astrophysics still i hve lot of work 2 do ok whn u do ur astrophysics i ned u 2 help me in Q(45) frm the old past papers i fel also oscillation calculations a bit confusing

ahan! Same here
ohkay no problem... Lets just do that now I can do bio later

ok thnx alot whn they ask how supernova is formed ? i wrote it ths way as i understood frm the book: During blue supergiant, hydrogen fusion takes place and whn its completed it becmes a red giant. Nuclear fusion of heavier atoms takes place and whn iron is formed there is no more release of energy therefore as the gravity pull becmes significant ths causes the star 2 collapse 2 a high density and explodes forming a supernova is tht correct?

Gimme a sec, i'll just solve the question n no problem

Which question again? I solved Q45 from the question u gave me but it doesnt have this

 

[*Sandra*]

Which question again? I solved Q45 from the question u gave me but it doesnt have this

no i don kno i saw it a number of times bt the que is how supernova forms and i wrote tht ans i send u is tht correct? and how did u solve q45 4 the 1st part?
