The treatment of a particle in a one-dimensional box can be extended to a two-dimensional box of dimensions L _ { x }L x and L _ { y }L y yielding the following expression for energy: E = \frac { h ^ { 2 } } { 8 m } \left( \frac { n _ { x } ^ { 2 } } { L _ { x } ^ { 2 } } + \frac { n _ { y } ^ { 2 } } { L _ { y } ^ { 2 } } \right)E= 8mh 2( L x2n x2+ L y2n y2)The two quantum numbers independently can assume only integer values. Consider an electron confined to a two-dimensional box that is 8.00 nm in the x direction and 5.00 nm in the y direction. a. What are the quantum numbers for the first three allowed energy levels? b. Calculate the wavelength of light necessary to promote an electron from the first excited state to the second excited state.

i think   the answer is c hope i'm right

he uptake of drugs from the intestine is often strongly influenced by diffusion. for example, consider a water-insoluble steroid for treating inflammation that is solubilized in aggregates of detergent molecules, called micelles. these micelles, aggregates of 80 soap molecules, have a molecular weight of 24,000, a diameter of 2.6 nm, and a charge of -27. the positively charge ions (counterions) in this system are na".

explanation:

two years ago, when picking flowers in the mountains back of yosemite valley, i found a book. it was blotted and storm-beaten; all of its outer pages were mealy and crumbly. the paper seemed to dissolve like the snow beneath which it had been buried, however; many of the inner pages were well preserved. and although all were more or less stained and torn, whole chapters were easily readable. this is the condition of the great open book of yosemite glaciers today; its granite pages have been torn and blurred by the same storms that wasted the castaway book.
