The diagram shows three vectors. Three vectors drawn on the x y plane. The first vector is 8 blocks long drawn in the positive x direction along the x axis and labeled P Subscript x Baseline. The second is drawn tail to tip method, is 6 blocks high, drawn north and labeled P Subscript y Baseline. The last is drawn from the tail of the first to the head of the second and labeled P. The angle between P and P Subscript x Baseline is labeled theta. Which best describes a relationship among the vectors? Vectors P and Py are components of vector Px. Vectors Px and Py are components of vector P.

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

Which terms describe the purpose of antennas on devices that use radio waves? transmit and receivemodify and amplifyamplify and receivemodify and transmit

A10nc charge sits at a point in space where the magnitude of the electric field is 1500 n/c. what will the magnitude of the field be if the 10 nc charge is replaced by a 20 nc charge? assume the system is big enough to consider the charges as small test charges.
