which option? thanks! A 3.50-eV electron is incident on a 0.40-nm barrier that is 5.67 eV high. What is the probability that this electron will tunnel through the barrier? (1 ev 1.60 x 10-19 J, m el 9.11 x 103 kg, h-1.055 x 1034 J,h 6626x 10-34J s) 1.5 x 10-3 9.0 x 10-4 1.2 x 10-3 1.0 x 10-3 2.4 x 10-3 MacBook Pro
An electron with a kinetic energy of 47.34 eV is incident on a square barrier with Ub = 56.43 eV and w = 2.000 nm. What is the probability that the electron tunnels through the barrier? (Use 6.626 ✕ 10−34 J · s for h, 9.109 ✕ 10−31 kg for the mass of an electron, and 1.60 ✕ 10−19 C for the charge of an electron.)
The energy of a proton is 1.0 MeV below the top of a 1.2-MeV-high energy barrier that is 6.8 fm wide. What is the probability that the proton will tunnel through the barrier? (1 eV = 1.60 x 10-19 J, Mproton = 1.67 x 10-27 kg, -h = 1.055 x 10-34 J·s, h = 6.626 x 10-34). s) 1) 11% O2) 9.1% O 3) 14% 4) 7.5%
Bob places a neutrally charged conducting ball next to a large, charged plate. The conducting ball is weakly attracted to the plate. What is the net charge on the plate? 1. a) Positive b) Negative c) Neutral (i.e., zero charge) d) Either positive or negative, but it is impossible to tell which A +1 C charge is at the origin, and a second +1 C charge is at position (x,y)-(2 m, 0). How much work is required to move the...
