Considering a spherical galaxy, with a volumetric mass density s from the center of the galaxy, given by p(s)= c/(1+s^3)
where c is a constant. let c=27.4
how do I determine the total mass M enclosed within a distance r to the galactic center using spherical shells?
This question was similar - it was probably yours. Does it help?
If not you will probably waits till Alan is on. He is the only one on here that can usually answer questions at this level. I would not expect him to be on for several hours.
Hay, wait just a minute . . .
That might have been true until I (we) joined the forum.
This might take me a few (dozen) hours to figure out. Maybe only a couple of hours if we chimps brainstorm.
If we really get in a pinch, Chimp Ayumu is skilled in high-level maths, and she helps us sometimes.
I like her, but some of the board members don’t because she makes us look kind of dumb.
We really need a fulltime, high-level mathematician, but she won’t join our board. She says we couldn’t grow enough bananas to get her to join.
We know how to count bananas, though.
We probably don't have enough bananas to satisfy Chimp Ayumu....however....we DO stock quite a quantity of peanuts......as long as she promises not to get any (spherical) shells on the floor......
