From the Heisenberg uncertainty principle, the position and momentum of a particle can be measure exactaly simultaneously.
Therefore, the correct option is position and momentum.

Which of the following are valid regarding the Uncertainty Principle? If a statement is invalid, write a brief statement indicating why. (a) It states that you cannot simultaneously measure both the position and momentum of a particle to infinite precision. (b) It arises from the wave nature of particles. (c) If the uncertainty in a particle’s momentum is determined to be ∆p, then the maximum uncertainty in its position must be ∆x = ~ 2∆p . (d) It implies that...
1. The Heisenberg Uncertainty Principle states that it is impossible to simultaneously determine both the momentum of an electron and its position in space. Why not? (Don't just re-state the Principle.)
according to the Heisenberg uncertainty principle, if the operator for two physical properties do not commute then. (pick 1 of the 4) (A) nothing can be said about the two operators. (B) the measurement uncertainties in the two properties will be the same. (C) both properties can be measured exactly. (D) the product of the measurement uncertainty of the two properties is greater than or equal to h/2pi

Part B The uncertainty ?p sets a lower bound on the average momentum of a particle in the nucleus. If a particle's average momentum were to fall below that point, then the uncertainty principle would be violated. Since the uncertainty principle is a fundamental law of physics, this cannot happen. Using ?p=2.1×10?20 kilogram-meters per second as the minimum momentum of a particle in the nucleus, find the minimum kinetic energy Kmin of the particle. Use m=1.7×10?27 kilograms as the mass...
