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 =...
