The uncertainty principle states that (a) no measurement can be perfect because it is technologically impossible to make perfect measuring instruments. (b) it is impossible to measure exactly where a particle is, unless it is at rest. (c) it is impossible to simultaneously know both the position and the momentum of a particle with complete certainty. (d) a particle cannot actually have a completely certain value of momentum.

    (c) it is impossible to simultaneously know both the position and the momentum of a particle with complete certainty.

    Explanation:

    According Heisenberg uncertainty principle, "it is impossible to simultaneously know both the position and the momentum of a particle with complete certainty".

    ΔxΔp ≥ h/4π

    where;

    Δx is uncertainty in position

    Δp is uncertainty in momentum

    h is Planck's constant

    Therefore, the correct option is "C"

    (c) it is impossible to simultaneously know both the position and the momentum of a particle with complete certainty.
