I’m rushing a lot of work right now… I do one of the
easier questions first:
Chapter 14 Prob 79
0.652mm = 0.000652m
Vol of bubble = 4/3 πr3 = 1.16*10^(-9) m3
Using Archimedes principle, upward force on bubble =
998 * 1.16*10^(-9) * 9.81 = 1.14 * 10^(-5) N
So, using F = ma at that particular spot in time (vol
of bubble will change as it goes higher),
M = 3.09*10^(-5) kg
