Homework Statement The spectroscopic dissociation energy of 127-I2 is 1.542eV. What wavelength of light would be needed to dissociate the molecule and have the atoms move apart at velocities of 1000 m/s? Homework Equations The Attempt at a Solution What I did was convert 1.542eV...

Thanks for the input guys

can anyone help me with this integration integral (dx)/(x^3+x) i tried solving it with partial integration and got stuck when i got find B and C...this was what i did = integral (dx)/[x(x^2 + 1)] = 1/[x(x^2 - 1)] = A/x + (Bx+C)/(x^2 + 1) => 1 = A(x^2 + 1) + (Bx+C)(x) => 1 =...
