Which was a limitation of the Bohr model of the atom?

It was valid only for single electron atoms like Hydrogen

It stated that only certain energies were allowed for electrons.

It described the electron as a wave and a particle.

The emission spectra is produced when

electrons release energy as they return to the ground state.

electrons release energy as they move to their excited state.

electrons absorb energy as they move to their excited state.

electrons absorb energy as they return to the ground state.

The difference between a car hitting a wall vs. a car hitting a hay stack is

the collision time of the car hitting the hay stack is greater

the Impulse on the car hitting the wall is greater

the change in momentum of the car hitting the wall is greater

the force on the car hitting the hay stack is greater

Energy is lost during this type of collision

energy is lost in both types of collisions

Momentum is conserved in this type of collision

momentum is conserved in both types of collisions

In this type of collision, objects tend to "stick" together.

They "stick" together in both types of collisions
