Quantized Energy of Molecules: Minimum Energy to Break Apart

AI Thread Summary
The discussion revolves around determining the minimum energy required to break a molecule apart from its ground state, which is at -2.5 eV. To transition to an unbound state, the energy must exceed this negative value, indicating that energy input is necessary to overcome the attractive forces holding the molecule together. Participants clarify the significance of the negative ground state energy, which represents a bound state, and the need for positive energy to achieve an unbound state. The conversation highlights the importance of understanding quantized energy levels in molecular physics. Ultimately, the minimum energy required to break the molecule apart is 2.5 eV.

Homework Statement


The graph below shows all of the quantized energies (bound states) for one of these molecules. For this molecule, E0 = -2.5 eV, E1 = -1.20 eV, E2 = -0.72 eV, and E3 = -0.30 eV. What is the minimum amount of energy required to break a molecule apart, if it is initially in the ground state? (Note that the final state must be an unbound state; the unbound states are not quantized.)

What does it mean that the ground state energy is negative 2.5 eV?
 
oh i get it now thanks
 

Thread 'Errors and significant figures'

I multiplied the values first without the error limit. Got 19.38. rounded it off to 2 significant figures since the given data has 2 significant figures. So = 19. For error I used the above formula. It comes out about 1.48. Now my question is. Should I write the answer as 19±1.5 (rounding 1.48 to 2 significant figures) OR should I write it as 19±1. So in short, should the error have same number of significant figures as the mean value or should it have the same number of decimal places as...

Thread 'A cylinder connected to a hanging mass'

Thread 'A cylinder connected to a hanging mass'

Let's declare that for the cylinder, mass = M = 10 kg Radius = R = 4 m For the wall and the floor, Friction coeff = ##\mu## = 0.5 For the hanging mass, mass = m = 11 kg First, we divide the force according to their respective plane (x and y thing, correct me if I'm wrong) and according to which, cylinder or the hanging mass, they're working on. Force on the hanging mass $$mg - T = ma$$ Force(Cylinder) on y $$N_f + f_w - Mg = 0$$ Force(Cylinder) on x $$T + f_f - N_w = Ma$$ There's also...
