Homework Statement Im trying to find the uncertainty for a log function. I have that f = 20log(V_in/V_out) and i want to know (delta)f Homework Equations f = 20log(V_in/V_out) The Attempt at a Solution I was going to do it the calculus way: f = 20log(V_in) -20log(V_out)...

hi, here's the question: a rod in the xy plane has it's ends at (0,0) and (L,0). It has a uniform charge per unit length (lambda). Find the electric field on the x-axis for 0 < x < L. solution attempt: dEx = dE = kdQ/r^2 dQ = lambda*ds = (Q/L)*dx now i took my r = (L - a -...

Homework Statement A hypothetical substance has an isothermal compressibility k = a/v and an expansivity B = 2bT/v where a and b are constants and v is the molar volume. Show that the equation of state is v-bT2+aP = g where g is a constant. Homework Equations k= -v(dP/dv)T B =...
