d. Indicate whether the following wavefunctions are acceptable or not. In each case, explain your A,...
Which of the following are acceptable wavefunctions for a particle in a one-dimensional box? Check all that apply. ψ(x) = C(1 - sin(nπx/a)) ψ(x) = Acos(nπx/a) + Bsin(nπx/a) ψ(x) = E/cos(nπx/a)ψ(x) = D(a - x)xψ(x) = Cx3(x-a)

Question 3 please + (20) 3. Indicate whether the reasoning of each of the following statements is correct or incorrect. Explain why or why not in each case. (Note: For an "if-then" statement, you do not need to verify that the hypothesis of the statement is true, nor come to any final conclusion ab f(x) is irreducible. Just indicate whether the conclusion correctly follows from the assumptions.) a) f(x) = +422 - 2x - 20 is irreducible in Qlx) by...
6. Indicate whether each of the following statements is true or false, and explain your reasoning? a. One mole of NH; weighs more than one mole of H2O. b. There are more carbon atoms in 40 grams of CO2 than in 12 grams of diamond (a form of pure carbon). c. There are equal numbers of nitrogen atoms in one mole of NH3 and one mole of N2. d. The number of Cu atoms in 100 grams of Cu(s) is...
fill the blank, and please explain why,thanks. Check whether the binomial approximation is acceptable in each of the following hypergeometric situations. Check the accuracy of your approximation by using Excel to find the actual hypergeometric probability. (Round "n/N" answers to 2 decimal places and other answers to 4 decimal places.) a. N= 100, n= 4, s= 50, PIX = 3) b. N= 200, n= 13, s = 75, PIX = 3) c. N= 160, n= 13, s= 19, PIX= 2)...

(2 points each) Indicate whether each of the following statements are valid or invalid function declarations (prototypes) by highlighting your answer choice (Are they syntactically correct?). a) double change( X, Y); answer: Valid Invalid b) char sign(double x); answer: Valid Invalid c) int max(int x, int y, int z) answer: Valid Invalid 2. (2 points each) Indicate whether each of the following statements are syntactically valid or invalid function headers by highlighting your answer choice. a) double change( X,...
Question 2: Indicate whether each of the following statements is true or false and explain concisely why. 2. In a OLS output ġ=.5+1.2log(x), the slope 1.2 is correctly interpreted as "a 1.2 percent increase in x is associated with a 1 unit increase in y, on average."
