If the position of an electron in space has a known uncertainty of 1.0 x 10^-13, what is the smallest uncertainty of the momentum of the same electron?
If the position of an electron in space has a known uncertainty of 1.0 x 10^-13,...
If an electron's position is known with small uncertainty, then the Heisenberg Uncertainty Principle predicts that .. O its momentum can be known with a small uncertainty the uncertainty in its position divided by the uncertainty in its momentum is larger than a fixed value its momentum can only be known with a large uncertainty -/1 points Which is correct? O most of an atom's mass and volume are in the nucleus which has a positive charge most of an...
What is the uncertainty in the position of an electron when its velocity is known to 5% the speed of light? A. 1 x 10-22 b. 4 x 10-42 c. 4 x 10-12 d. 2 x 10-43
5) Consider an electron located on the x-axis such that the uncertainty in its position is 1.00 Angstrom. What is the minimum uncertainty in its momentum along the x axis? Give the answer in units of (kg m)/sec 6) If the work function of a metal is 2.00 x 10-19 J, what is the frequency of the light required to just eject an electron from the metal, that is, such that the ejected electron has zero kinetic energy? Give the...
h where ħ=__=1.054 x 10-34 Js 27 Uncertainty principle Question) Uncertainty in position of an electron is 1 nm. Estimate the minimum uncertainty in momentum and the corresponding kinetic energy.
An electron has a momentum p? 1.9×10?25 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
An electron has a momentum p≈ 1.7×10−25 kg⋅m/s. What is the minimum uncertainty in its position that will keep the relative uncertainty in its momentum (Δp/p) below 2.0%? Place final answer in 2 significant figures and convert answer to nanometers. The answer is NOT 15nm or 16nm from: x = h / [(4pi)(2%)(p)] = (6.626×10−34) / [(4pi)*(0.02)(1.7x10−25)]) = 15.5nm. Do not write this as the answer.
The position of an electron is known to within 11.3 angstroms. What is the minimum uncertainty in its velocity? Repeat the calculation for a lithium atom.
3) Suppose the instantaneous position of an electron of an electron moving along the x-axis is 10 A. The velocity of electron is 10sm/s. What is the minimum uncertainty in momentum? In velocity?, In kinetic energy? (Use your uncertainty relations)
The uncertainty in the position of an electron is an experiment is 8.1 x 10-9 m. Calculate the uncertainty in the electron's velocity, in units of m/s.
