Lol mish laha ldaraji :P
U already spelled my name .. wtvr
Anyway umm trace it bak may june 03 q 3 b P1V1=P2V2
Do we convert cm^3 to m^3 since Pa (N/m^2)??

Shazizzzle:
Two things.
First of all, aren't beta particles electrons? Why, then are they emitted from the NUCLEUS, as states Q38 of M/J 2008, P1? :S ???
Secondly, O/N 2005, Q36, P1, I know you said that a neutron splits to form an electron and proton, but why can't we use the simple beta emission formula here. The -1B particle, where A remains A, and Z + 1? :S Isn't that formula for unstable nuclei too? Because, a stable one doesn't emit anything.
