Two coils are wound around the same cylindrical form. when the current in the first coil is decreasing at a rate of -0.250 a/s, the induced emf in the second coil has a magnitude of 1.65 x 10^-3 v. a) what is the mutual inductance of the pair of coils? b) if the second coil has 30 turns, what is the flux through each turn when the current in the first coil equals 1.25 a? c) if the current in the second coil increases at a rate of 0.3 a/s, what is the magnitude of the induced emf in the first coil?

Consider the particle-in-a-box problem in 1d. a particle with mass m is confined to move freely between two hard walls situated at x = 0 and x = l. the potential energy function is given as (a) describe the boundary conditions that must be satisfied by the wavefunctions ψ(x) (such as energy eigenfunctions). (b) solve the schr¨odinger’s equation and by using the boundary conditions of part (a) find all energy eigenfunctions, ψn(x), and the corresponding energies, en. (c) what are the allowed values of the quantum number n above? how did you decide on that? (d) what is the de broglie wavelength for the ground state? (e) sketch a plot of the lowest 3 levels’ wavefunctions (ψn(x) vs x). don’t forget to mark the positions of the walls on the graphs. (f) in a transition between the energy levels above, which transition produces the longest wavelength λ for the emitted photon? what is the corresponding wavele
