If a particle’s momentum uncertainty, what is the uncertainty in its position. Very briefly, what does this result mean?

What is the Compton effect? What is measured in observations of the Compton effect? How does this differ from the expectations of classical physics? At what condition for incident radiation can the effect be observed? What important property of light does the Compton effect demonstrate? How does it give evidence of electromagnetic radiation`s particle nature?

What is the minimum uncertainty in its position that will keep the relative uncertainty in its momentum (p/p) below 2.0%?

An electron has a momentum p= 1.9×1025 kg m/s. What is the minimum uncertainty in its position that will keep the relative uncertainty in its momentum (p/p) below 2.0%? Answer is in nm

Exercise 6: A) How does the Heisenberg Uncertainty (with momentum and position) force us to abandon a deterministic universe? B) In what important ways is the Bohr model of the atom incompatible with quantum theory? Include the concept of orbits and what is known about angular momentum.

The most basic explanation for the Heisenberg Uncertainty Principle is that the momentum and position of...

The most basic explanation for the Heisenberg Uncertainty Principle is that the momentum and position of a quantum particle is not very distinct when an attempt is made to measure them together. But what is it that causes the uncertainty? Because if there is no change in the momentum, then it would be the same as measuring the two separately. So what causes this change in the instantaneous perceived momentum. A change in mass? Velocity? Or net composition of the...

Minimum uncertainty in momentum of bullet

A 12 gram bullet leaves the barrel of a rifle at 180 m/s. If the vertical position of the bullet is known to a precision of 0.65 cm (radius of the rifle's barrel). What is the minimum uncertainty in the bullet's vertical momentum?

At what position does a pendulum have its maximum kinetic energy? At what position does a pendulum system have its maximum potential energy (Earth is in the system) ? Why must the angular displacement of a pendulum be relatively small? If a 3kg bowling ball were suspended from a 5m piece of fishing line, what would be the period of oscillation? Now, if instead of fishing line, that same 3kg bowling ball were suspended from a 5m cable with a...

Use the Heisenberg uncertainty principle to estimate the uncertainty in momentum resulting from confining an electron to an atom (~10-10 m) and to the size of an atomic nucleus (~10-15 m). Calculate the corresponding uncertainty in the energy (in eV) of the confined electron and briefly comment on the physical implications of your results.

What is the uncertainty of the position of the bacterium? Express your answer with the appropriate units. -------- A student is examining a bacterium under the microscope. The E. coli bacterial cell has a mass of m = 1.10 fg (where a femtogram, fg, is 10−15g) and is swimming at a velocity of v = 9.00 μm/s , with an uncertainty in the velocity of 7.00 % . E. coli bacterial cells are around 1 μm ( 10−6 m) in...
