Which of the following statements are true for the Bohr model of the atom? (There could be more than one correct choice.)
A) The spacing between all the electron shells is the same.
B) The energy difference between all the electron shells is the same.
C) As we look at higher and higher electron shells, they get closer and closer together, but the difference in energy between them gets greater and greater.
D) As we look at higher and higher electron shells, they get farther and farther apart, but the difference in energy between them gets smaller and smaller.
E) There is no general pattern in the spacing of the shells or their energy differences.

A 480-kg car moving at 14.4 m/s hits from behind a 570-kg car moving at 13.3 m/s in the same direction.
If the new speed of the heavier car is 14.0 m/s, what is the speed of the lighter car after the collision, assuming that any unbalanced forces on the system are negligibly small?
A) 10.5 m/s B) 13.6 m/s C) 19.9 m/s D) 5.24 m/s
