Particles of mass m and energy e= v/2 potential barrier at are incident upon a x-0. (v(x)= 0 for x< 0, v(x)= v for x> 0) if the particles' state is described ( ikx-iwt) be (hint: j (ab- (20) 2mi ap(ikjz - iwt) by 1) what is k? (4) what's the transmission and reflection at the interface? (8) 2) what is the particle density at x(> 0)? (remember, dn= 1b| d)

Light traveling in a medium with a refractive index 1.19 is incident on a plate of another medium with index of refraction 1.79. at what angle of incidence is the reflected light fully polarized?

Aboat radioed a distress call to a coast guard station. at the time of the call, a vector a from the station to the boat had a magnitude of 45.0 km and was directed 15.0° east of north. a vector from the station to the point where the boat was later found is = 30.0 km, 15.0° north of east. what are the components of the vector from the point where the distress call was made to point where the boat was found? in other words, what are the components of vector c = b - a?

Which lists the pairs of plates in order from least to greatest in terms of the work done to move the electron?
