Hw 1.43 (sixth edition)

Postby MaryBanh_2K » Thu Nov 07, 2019 9:45 am

1.43 What is the minimum uncertainty in the speed of an electron confined to within a lead atom of diameter 350. pm? Model the atom as a one-dimensional box with a length equal to the diameter of the actual atom.

In this problem, does the 350 pm represent delta x? Will it always be talking about the diameter of an object?

Yes, usually Delta X is the diameter of the atom. So this means if they give you radius, you have to multiply by 2 to get the diameter. Also remember units have to be in meters so convert if necessary.
