The acoustic level for normal conversation is 60 dB SPL A) What is the corresponding force on the eardrum? Assume the diameter of the the eardrum is 8.4 mm. B) We consider that this force is transmitted integrally to the oval window. The surface of the oval window is 0.03 cm2. What is the corresponding pressure? C) The pressure at the eardrum is amplified further as a result of the lever action of the ossicles. Calculate the pressure at the oval window D) Calculate the amplification realized by the middle ear in dB
The source of all sounds is something that is Group of answer choices vibrating. undergoing simple harmonic motion. accelerating. moving.
If find $f'(x)$. $f'(x) =$ Find $f'(2)$. $f'(2) =$ Note: You can earn partial credit on this problem. $f(x) = \frac{7x^3 - 5}{x^4}$
Braniff, Inc. reported net income of $850,000 for 2015. Braniff sold 15,000 shares of treasury stock acquired in a previous year on July 1 and 15,000 new shares on November 1. At yearend, 180,000 shares were outstanding. Braniff had 20,000 shares of preferred stock outstanding all year. Braniff paid dividends of $0.25 per share on common stocks and $6 per share on its preferred stock. a) Calculate the basic earnings per share for 2015? (Round to cents.) b) If each share of preferred stock is convertible into 2 shares of common stock, what is the diluted earnings per share for 2015? (Round to cents.)
Refer the above demand curve, the demand function is: a. Q = 40 ? 2P b. Q = 80 ? 0.5P c. Q = 40 ? 0.5P d. Q = 80 ? 2P Assume peanut butter and jelly are complements. Ceteris paribus, an increase in the price of peanut butter will cause a (an): a. leftward shift in the demand curve for jelly. b. rightward shift in the demand curve for jelly. c. upward movement along the demand curve for jelly. d. downward movement along the demand curve for jelly.
Suppose that you perform an experiment on m different days. On each day, you make n + 1 measurements that should satisfy the following relations: aix = bi, i = 1,...,m, j = 1 for some x. Suppose that m ≥ n so that this system may have many solutions for x. You are interested in finding the solution with the smallest number of positive entries. (a) Formulate this problem as a mixed integer linear programming problem. (b) (GAMS) Consider the following instance: Cli1 Alj2 Clis Day 1 2 3 1 Day 2 3 2 Day 3 2 2 3 Ci5 bi 6 7 4 1 1 0 2 4 1 Solve the corresponding problem in GAMS. Upload your model file (gms) on Blackboard. On paper, briefly comment on the optimal solution returned by the solver (i.e., give a brief discussion of why the optimal solution returned by the solver is reasonable for the given problem)
Java program: Takes a linked list of any size. The program should determine if 3 subsets of the linked list exist where the sum of the integers in the first set minus the sum of the second set are equal to the sum of the second set minus the sum of the integers in the third set. Prints YES if exists. True: (Sum of set 1 - Sum of set 2) EQUALS (Sum of set 2 - Sum of set 3) ex: LL[5, 1, 5, 4] = YES set 1(5, 1) - set 2(5) = 1 set 2(5) - set 3(4) = 1
Given that s refers to a set, write a statement that attempts to remove the int value 11 from the set, but will do nothing if 11 is not in the set.
A Java method that creates a stack as input and stores integers in the stack. The method returns whatever is at the bottom of the stack (it could be anything). Just break the provided stack to provide a solution (do the same without breaking down the input stack).
In C++, we call: void f(double a, int n, double x[]); double x[5] = {6, 1, 3, 2, 4}; f(9.6, 3, x); In the fastcall convention, the first parameter is passed in register _____, the second in register _____, the third in register ____.
