Suppose that the speed of an electron traveling 1.0 km/s is known to an accuracy of 1 part in 10,000 (that is, within 0.01%). What is the minimum uncertainty in the position of this electron? (m electron = 9.11 × 10-31 kg, h = 6.626 × 10-34 J • s) I think the answer is 1.2 mm but want to see if I did this correctly please show all work if handwritten please write clearly.
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...
German physicist Werner Heisenberg related the uncertainty of an object's position (Ac) to the uncertainty in its velocity (Av) Δα 2 ΛπηΔυ where h is Planck's constant and m is the mass of the object. The mass of an electron is 9.11 x 10-31 kg. What is the uncertainty in the position of an electron moving at 7.00 x 10 m/s with an uncertainty of Av=0.01 x 10 m/s? Ax

5. (a) Assume that an electron is moving along an x-axis with a speed of u = 3.080 x 10-m/s measured to a precision of 0.6%. What is the minimum uncertainty (as allowed by the uncertainty principle in quantum theory) with which you can simultaneously mea- sure the position of the electron along the c-axis? Note that the electron mass is m = 9.110 x 10-31 kg. (b) The speed of a bullet is known to a precision of 0.43%....
Physical Chemistry 5. Because of their short wavelength, the resolution of an electron microscope can be made several 100-fold higher than that of a microscope based on light. They have thus become one of the most powerful techniques for studying macromolecules, assemblies of macromolecules, cellular organizations, and so on. Modern electron microscopes can emit a beam of electrons with a velocity of 1.5 x 10 m/sec. a) Enter the wavelength of an electron in this beam in meters and to...
