A thermometer has its term marked millimeter instead of degree celcuis .The lower fixed point is 30mm and upper fixed point is 18mm. Calculate degree celcuis when the thermometer records 45mm

What are segments of dna that code for a particular trait. a combination of dna and proteins make up what

Atrain departs from its station at a constant acceleration of 5 m/s. what is the speed of the train at the end of 20s?

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
