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
Homework Answers
uncertainty relation between two operators A andB is given as
AB
suppose we consider position X and momentum Px in place of A and B
we know that momentum and position does not commute. in fact [X,Px]=ih/2pi
hence substituting for A and B as X and Px we get
XPxh/2pi
correct answer is (D) the product of the measurement uncertainty of the two properties is greater than or equal to h/2pi

There is an uncertainty principle for energy and time ∆E∆t ≥ ¯h/2 . This relationship can be applied to the excited state energies and their lifetimes of atoms and molecules. a) Show that both sides of the expression for time-energy uncertainty relationship have the same units. b) If the lifetime of a molecule at its excited state is 1 nanosecond, what is the uncertainty of the energy (in eV) of this state? c) If a 10-femtosecond laser is used to...

The "best" result is always associated with the measurement with the smallest uncertainty. Measurement B has half the standard uncertainty of measurement A. Therefor e our 68 % coverage probability is associated with a smaller interval (83.44 g o 83.56 g) for measurement B than measurement A (83.38 g to 83.62 g). In other words we have better knowledge about the value of the measurand from measurement B, since we have the same coveroge probability associated with a norrower interval....

HayyaHalwa is an Omanis chocolate producer. HayyaHalwa has a factory with five production lines that can produce a wide range of sweets. HayyaHalwa has just hired 50 operational employees last two months. Due to high demand of chocolate, none of training organized for the employees. Over many years, HayyaHalwa has invested heavily to make their production processes more efficient, with a continual focus on improving efficiency, quality and health, safety and environmental performance. HayyaHalwa considered all requirements in production as...

This C++ Program consists of: operator overloading, as well as experience with managing dynamic memory allocation inside a class. Task One common limitation of programming languages is that the built-in types are limited to smaller finite ranges of storage. For instance, the built-in int type in C++ is 4 bytes in most systems today, allowing for about 4 billion different numbers. The regular int splits this range between positive and negative numbers, but even an unsigned int (assuming 4 bytes)...

INTRODUCTION The chemical and physical properties of substances are influenced by the way in which valence electrons are distributed and by the three-dimensional shape of the molecule or ion. X- ray and neutron diffraction, infrared, Raman and microwave absorption spectroscopy, as well as dipole moment measurements are used to ascertain the three-dimensional structure of a substance. Thus, techniques are available which can identify the geometry of substances. Results of these measurements generally...
