after visiting the needleton natural museum, irma was so fascinated by the reptile exhibit

that she got her very own pet lizard, irma bought a terrarium shaped like a rectangular prism

for her lizard to live in. the terrarium is 20 inches long, 15 inches wide, and 12 inches tall.

which equation can you use to find the volume of the terrarium, v?

20. 15 = 12v

v = 20. 15. 12

what is the volume of the terrarium?

write your answer as a whole number or decimal. do not round.

cubic inches

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

Examine the nuclear reacti why is this classified as a nuclear reaction rather than a chemical reaction? it is not balanced. a new compound is formed. a change has occurred in a nucleus. a new element has been formed.
