Anyone offer any help? sorry to bump so quickly

Homework Statement An insulated Piston-Cylinder device contains .6kg of H20 at 600kPa Initially the volume of the system is .6m3. Now an electric resistor is placed in the tank and turned on for 10 minutes until the volume doubles. Show this on a T-v diagram What is final temp? What is the...

Sorry I didn't mean to say that it closes in but that it is close for (as you stated) small values. But, for some reason the professor didn't tell us that this was the case and I'm unsure why they are only concerned with the smaller values Thank You for the input and help!

I figured out what was meant by approximation. As if you plot y=x and y=-tan(x) the points at which they cross close in on the values of pi*n/2 at odd n values. so k~(2n-1)*pi/2. which makes the Eigenfunction sin(kx)=sin[((2n-1)*pi*x)/2]

Homework Statement using X''(x)+ lambda*X(x)=0 find the eigenvalues and eigenfunctions accordingly. Use the case lambda=0, lambda=-k2, lambda=k2 where k>0 Homework Equations X(0)=0, X'(1)+X(1)=0 The Attempt at a Solution I know that for lambda=0 X(x)=C1x+C2 which applying the...
