Isotopes differ by the number of nucleons but have the same number of protons. Ok, I'm starting to see it. So, why do you subtract the nucleon atomic mass from the atomic mass difference? Isn't the difference in mass between two different isotopes already there? Or is it asking for the...

Homework Statement Two isotopes of a certain element have binding energies that differ by 5.03 MeV. The isotope with the larger binding energy contains one more neutron than the other isotope. Find the difference in atomic mass between the two isotopes.Homework Equations 1u=931.5MeVThe...

Homework Statement The same diffraction grating is used with two different wavelengths of light, λA and λB. The fourth-order principal maximum of light A exactly overlaps the third-order principal maximum of light B. Find the ratio λA/λB. Homework Equations sin theta = m lambda /...

mgh = 1/2mv^2 + 1/2IW^2 Tangent Velocity = rW W=Tangent V / r Substitute W and solve for h. h = (1/2V^2 + 1/3(Tangent V)^2) / g Tangent V = translational V h=3.18 I got it now, Thanks!

Homework Statement Starting from rest, a basketball rolls from the top of a hill to the bottom, reaching a translational speed of 6.12 m/s. Ignore frictional losses. Homework Equations (a) What is the height of the hill? (b) Released from rest at the same height, a can of frozen...
