The wave function of the electron within the well is of the form a cos( 2πx / λ ) where a is a normalization constant. what is the approximate value of λ, within about 10%? [note: although you can really only estimate it to within about this accuracy, the current version of smartphysics will require higher accuracy.] λ =

The answer is y is 0.05.

Explanation:

At cos(2x) and the left and right boundaries are at 400 pm.

At 0 pm = cos(2π × x ÷ ∧) = 1

So,

A has to be 0.075.

it looks like at 300 pm, y = 0.05.

0.05 = 0.075 × cos(2π × 300 pm ÷ ∧)

= 0.05.

b

step-by-step explanation:

to find the perimeter of the rectangle this is the expression:

x-9+x-9+3x-4+3x-4=138

if we simplify it:

8x-26=138

remember, 138 is what it all adds up to

the length is 11.5cm

the width is 57.5cm

the area is 661.25cm^2
