A 2m long stick is placed horizontally so it is balanced perfectly at a point in the middle. A 1.6kg mass is placed at the far left end of the stick. Where on the right side of the stick must a 4.1kg mass be placed so the entire system is in equilibrium? Be sure to specify if your position is measured from the center of the stick or from the end. Which of the masses produces a positive torque and which produces a negative torque? Explain your answer.

Water flows at a speed of 2.2m/s through a pipe whose radius is 0.23m. There is a constriction in the pipe which reduces the radius to 0.085m. What is the speed of the water through the constriction?

A solid sphere of mass M and radius R starts at the top of a hill of height = H. Starting from rest, it rolls without slipping down to the bottom of the hill. What is its linear speed Vlin (in terms of regular physics constants and the other variables given) when it reaches the bottom?

For this assignment, you will read one of the short stories listed below and write an analysis on how the elements of fiction that you have studied contribute to, work within, and/or enhance the chosen story. Analyze the fiction elements of character, setting, theme, irony, and symbolism.  This preliminary draft can include secondary sources. You must include evidence from the short story to support your analysis of it.    Story Choices: “The Tell-Tale Heart” by Edgar Allan Poe (posted in Canvas module) “Young Goodman Brown” by Nathaniel Hawthorne (pp. 392-403) “The Story of an Hour” by Kate Chopin (pp. 554-556) “A Rose for Emily” by William Faulkner (pp. 557-564)

Consider the following equation:             N2O4(g) ⇌ 2 NO2(g)    Kc = 5.8 × 10−3  If the initial concentration of N2O4(g) = 0.040 M and the initial concentration of NO2(g) is 0 M, what is the equilibrium concentration of N2O4(g)?

During this exam, you may create and work on an Excel Workbook file on Microsoft 365.  

A pediatric patient has received several rescue inhaler treatments at home and a couple of albuterol treatments in the ER but continues to show respiratory distress with bilateral expiratory wheezing and chest retractions. What should the respiratory therapist recommend now?   I. Continuous aerosolization of albuterol (Ventolin) at 10mg/hr II. Give another 1.25 mg of albuterol (Proventil) III.
