Question 8 Cedrick's credit card was stolen, and he did not realize that it was stolen until he received his most recent billing statement. He contacted the credit card company immediately after he read his statement. Fraudulent charges were as follows: \$250 for a Blue-ray player, \$600 for a new set of tires, \$200 cash withdrawal, and \$40 in interest charges on the above items. He did not carry credit card insurance. How much is Cedrick's potential maximum liability? \$40.00 \$50.00 \$850.00 \$1,050.00 \$1,090.00

Question 25 1 pts During speciation, the phenomenon of stabilization is likely to occur when, after a period of geographic isolation, two populations meet again and _____ ? an increasing number of viable, fertile hybrids is produced over the course of the next 100 generations. ? no reproduction occurs in the hybrid zone. ? an increasing number of infertile hybrids is produced over the course of the next 100 generations. ? the species will consequently have a relatively short existence compared with other species.

Please explain number three. Commutator of two Operators A and B [A,B] = AB - BA. Examples: A = x and B = P = -ih/0x [x,p]y = xp - pxy = -ihx = ihy axOx In the same way, y[y,p]y = ihy [p]y = ihy Since this is true for all State Vectors w, [x,p] = ih [y,p] = ih [p] = ih Also, [x,p] = [x,p] = 0 [y,p] = [yp,p] = 0 [p] = [.p] = 0 A = F and B = p = -ihV [F,p]y = -ih [FVy - VFw] = ihvF)y = ihy [Fp] = ih ar ie.eJ [1,E] = -ih 153 Re TMe f Com

Distortion. a. Use the following script to create an amplified tone which is subsequently clipped (this is basically how the output of amps saturate). tone2=2*tone; tone8=8*tone; for i=1:40960; if abs (tone2 (i))>1, tone2(i)=sign (tone2(i)); % clips signal to +/-1 volt; sign = 1 if value is positive and -1 if value is negative end if abs (tone8(i))>1, tone8 (i)=sign (tone8(i)); end end plot(t(1:N), tone (1:N),t(1:N),tone2(1:N), t(1:N), tone8 (1:N)) b. Adjust the vertical scale of the plots to +/- 1.2 volts so you can clearly see the clipping effect. Submit your plot and discuss how the three signals differ in the time domain. c. Create and plot (in 3 subfigures) the magnitude spectra (per Part 1) for the three signals. Submit your figure and discuss how these signals differ in the frequency domain. d. Listen to the three sounds (use soundsc). Discuss what you hear for each tone and how that relates to what you observe in both the time and frequency domain representation of the signal.

Imagine you are studying an enzyme with two possible conformational states. One is 'active'. The other is 'inactive'. You do a series of experiments to determine that the enthalpy of the active state is 4.000 kcal/mol more favorable than that of the inactive state. You also determine that the entropy of the inactive state is 0.0127 kcal/molâˆ™K more favorable than that of the active state. 1. Which form of the enzyme is favored at physiological temperature? 2. How do you know? (This should involve math) 3. What is the ratio of active to inactive states at physiological temperature? 4. What if you run a 6Â° fever? 5. What might this imply about proteins in cold-blooded organisms versus warm-blooded organisms?
