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.)

TL;DR Summary: I would like to know the voltmeter readings on the two resistors separately in the picture in the following cases , When one of the keys is closed When both of them are opened (Knowing that the battery has negligible internal resistance) My thoughts for the first case , one of them must be 12 volt while the other is 0 The second case we'll I think both voltmeter readings should be 12 volt since they are both parallel to the battery and they involve the key within what the...

Thread 'Struggling to make relation between elastic force and height'

Hello guys this is what I tried so far. I used the UTS to calculate the force it needs when the rope tears. My idea was to make a relationship/ function that would give me the force depending on height. Yeah i couldnt find a way to solve it. I also thought about how I could use hooks law (how it was given to me in my script) with the thought of instead of having two part of a rope id have one singular rope from the middle to the top where I could find the difference in height. But the...
