An electron is trapped in an infinitely deep one-dimensional well of width 0.288 nm. Initially the electron occupies the n = 4 state. (a) Suppose the electron jumps to the ground state with the accompanying emission of a photon. What is the energy of the photon? eV (b) Find the energies of other photons that might be emitted if the electron takes other paths between the n = 4 state and the ground state. 4 → 3 in eV 4 → 2 in eV 3 → 2 in eV 3 → 1 in eV 2 → 1 in eV

Solve the Laplace equation ∇^2(u)=0 (two dimensions so ∂^2/∂a^2 + ∂^2/∂b^2) where the boundaries of the rectangle are 0 < a < m, 0 < b < n with the boundary conditions:
u(a,0) = 0
u(a,n) = 0
u(0,b) = 0
u(m,b)= b^2

The accompanying table provides the data for 100 room inspections at each of 25 hotels in a major chain. Management would like the proportion of nonconforming rooms to be less than 2%. Formulate a one-sample hypothesis test for a proportion and perform the calculations using the correct formulas and Excel functions. Use a level of significance of 0.05.

Is there sufficient evidence at the 0.05 level of significance that the proportion of nonconforming rooms to be less than 2%?
Determine the null hypothesis, H0, and the alternative hypothesis, H1. Then compute the test statistic and p-value. Finally, state the conclusion.

i have this problem write an application that evaluates the
factorials of the integeres from 1 to 5 . i have this
!
control.WriteLine( "n\tn!;n");
for (in number=1; number <=5; number ++);
{
int factorail=1:
for (int 1=1; i<=number;1++);
factorial *=1:
Console.Writeline("{0}\t{1}".number,factorial);
output
n n!
1 1
2 2
3 6
4 24
5 120
I understand how the first row is printed.
the first 1 in because the intfactorial is 1
the #2 if printed becasue in number =1; number<=5; number ++ =2
then it runs again number=2; number <=5; number ++ ) number is 3
then it runs again number=3; number <=5; number ++) number is 4
then it runs again number=4); njmber <=5; number ++) number is 5 and then ends because it hits <=5 and becomes true
so it goes to the next
for (int i=1; i<=number; i++
factorial *=1;
not sure how this works or comes up the mulipliers
