(a)A soccer ball with a stationary mass of m = 1 kg is located
in the center of the soccer field. If the soccer ball has moved by
0.1 nm (delta x is 0.1nm ), use the uncertainty principle to
obtain speed uncertainty.
(b) If the student did not have a measuring device (recorder)
that can record a soccer ball moving at 1 nm, how long would it
take to record a changing length of 1 nm?
(c) When an electron belongs to a semiconductor device having a
channel length of 5 nm, it may be referred to as a position
identity.What is the speed uncertainty of the electron?
