The most probable location of the particle

The exact location of the particle

The energy of the particle

The momentum of the particle

If the particle exists or not

Second excited state.

Ground state.

Fourth excited state.

Not enough information to solve the problem.

The energy is described by discrete energy levels, and the particle can only have energy that corresponds to these levels, positive or negative.

The energy of the particle can be anything, positive or negative.

The energy must be negative and continuous.

The energy must be positive and continuous.

There is nothing constraining the energy of the particle.

represents the probability distribution of the particle as a function of time

represents the position of the particle as a function of time

represents the square of the particle's position as a function of time

represents the time-averaged position of the particle as a function of time

represents the energy of the particle as a function of time
