Δpmin =_______kg⋅m/s Part B What is the kinetic energy of a proton whose momentum is equal to this uncertainty (Δp=p)? Express your answer using two significant figures. K=________ meV please!!
An electron has a momentum p? 1.9×10?25 kg?m/s. What is the minimum uncertainty in its position that will keep the relative uncertainty in its momentum (?p/p) below 2.0%? Answer is in nm
An electron has a momentum p≈ 1.7×10−25 kg⋅m/s. What is the minimum uncertainty in its position that will keep the relative uncertainty in its momentum (Δp/p) below 2.0%? Place final answer in 2 significant figures and convert answer to nanometers. The answer is NOT 15nm or 16nm from: x = h / [(4pi)(2%)(p)] = (6.626×10−34) / [(4pi)*(0.02)(1.7x10−25)]) = 15.5nm. Do not write this as the answer.

Part B The uncertainty ?p sets a lower bound on the average momentum of a particle in the nucleus. If a particle's average momentum were to fall below that point, then the uncertainty principle would be violated. Since the uncertainty principle is a fundamental law of physics, this cannot happen. Using ?p=2.1×10?20 kilogram-meters per second as the minimum momentum of a particle in the nucleus, find the minimum kinetic energy Kmin of the particle. Use m=1.7×10?27 kilograms as the mass...
