Hello ..I have a question which I am sure is easy to answer. It has been a long time since I had physics. In a youtube video located here:
http://www.youtube.com/watch?v=dAI8BgCudDQ&list=UU1I__Q1k7NgSZE4PByLfQEg&index=54&feature=plcp
She writes a relationship at 4 min which is
dm=d(M)/(m+M).
Could someone tell me how she gets that? Thank you in advance...
