Jj thomas' model contained electrons.
The current model contains a nucleus with electrons orbiting around it. :)
It would have to be c because it is a chemical change. your welcome!!!!!
Using conservation of energy and momentum we get m1*v1=(m1+m2)*v2 so rearranging for v2 and plugging the given values in we get:
(200000kg*1.00m/s)/(21000kg)=.952m/s
That is very true, but what is the question asking you.
