1. The problem statement, all variables and given/known data A glass hydrometer of mass m floats in water of density p. The area of the neck of the hydrometer is A. The resonance frequency for vertical oscillations is given by: f=1/2pi(apg/m)^0.5 Calculate the fractional change in the resonance frequency when the temperature changes from 20 degrees celcius to 30 degrees celcius. [For glass the coefficient of linear expansion is 9*10^-6 degrees^-1 and for water, the coefficient of volume expansion is 2*1-4 degress^-1 Any ideas on how i do this. If you could be quite graphical in the method this would be helpful as I have many questions of this sort to go though.
