Question: [ 2 / 4 Points ] When we first encounter these atoms, they have a total energy E _ ( 1 ) as shown on

[2/4 Points]
When we first encounter these atoms, they have a total energy E_(1) as shown on the figure. Which of the following statements is true? (Select all that apply.)
The atoms have negative kinetic energy.
They are in a bound state.
The total energy of the molecule is positive.
The total energy of the molecule is negative.
If the molecule made up of these two atoms is at rest, each atom has 0 kinetic energy.
The total energy of the molecule is zero.
(Select all that apply.)
They are no longer in a bound state.
They are less tightly bound than they were before.
Their binding energy has not changed.
They are more tightly bound than they were before.
What can you say about the average separation between the two atoms when they are in the states shown on the diagram? (Select all that apply.)
When the atoms in the molecule have an energy E_(2) the atoms are on average closer together than when they have an energy E_(1).
When the atoms in the molecule have an energy E_(1) the atoms are on average closer together than when they have an energy E_(2).
In both states, the separation between the atoms remains fixed.
The atoms change their position more when they are in the state E_(2) than when they are in the state E_(1).
The atoms change their position more when they are in the state E_(1) than when they are in the state E_(2).
If the atoms were in the state labeled E_(1), which of the statements below is true? (Select all that apply.)
To shift them to the state with total energy E_(2), you would have to add E_(2)-E_(1) to their energy.
To pull them completely apart, you would have to add -E_(1) to their energy.
By pulling them completely apart, you would gain an energy E_(1) that you could use elsewhere.
To pull them completely apart, you would have to add E_(1) to their energy.
To shift them to the state with total energy E_(2), you would have to add E_(2) to their energy.
Please help me with the second and third question - thanks
