If the uncertainty in the position of a proton is 0.053 nm, what is the uncertainty in its speed? (h = 6.626  10-34 J  s, mproton = 1.67  10-27 kg)
 
  A) 2.2 m/s B) 0.60 km/s C) 1.2 km/s D) 0.98 km/s E) 37 m/s

Question 2

A simple series circuit consists of just a 3.4-F capacitor and an 80-mH inductor, with no appreciable resistance. At t = 0 the capacitor has charge 5.4 C and the current in the inductor is zero.
 
  (a) How long after t = 0 will the current in the circuit be maximum?
  (b) What will be this maximum current?
