Answer:
They are correct
Explanation:
According to the uncertainty principle, the uncertainty in the position of an object is directly proportional to its De Broglie wavelength.
The De Broglie wavelength of a baseball is about [tex]10^{-34}m[/tex], recall that the diameter of the atom is about to [tex]10^{-10}m[/tex]. Thus, the error in simultaneously determining the position and momentum of a baseball is infinitesimally small.
