QuestioN1 You are workingon a team that is building a lightweight, remote-controlled aircraft with the goal of lifting as much payload as possible. Your team has selected a design that will use a rectangular wing with a constant cross-section in the form of a high-lift airfoil. You are responsible for the initial sizing of the load carrying spar that runs the entire span of the wing. In flight, the spar acts much like a loaded cantilevered beam, as shown in...
8. The table below shows the relationship between stimulus voltage and tension developed. a. At what voltage does the muscle reach threshold voltage? At what voltage does the muscle start to have its strongest contraction? b. As you increase voltage, what is occurring in the sciatic nerve to produce stronger muscle contractions? What is the name for this event? c. Where does the "voltage" originate from in the human body? (3 points) Tension Developed (g) Stimulus Voltage (mV) 0.05 0.1...

Questions 1. Given the H NMR spectrum and molec- ular formula for each of the following compounds, deduce the structure of the compound, estimate the chemical shifts of all its protons using the parameters in Tables 22.3–22.5, and assign the NMR sig- nals to their respective protons. (a) C.H,,Cl; 1H NMR (CDC12): 8 3.33 (2H, s); 1.10 (9H, s) (b) C-H,,0,; 1H NMR (CDC12): 8 3.88 (1H, s); 2.25 (3H, s); 1.40 (6H, s) (C) CH,,0,; 1H NMR (CDC1,): 8...
6.Use Exponential smoothing forecasts with alpha of 0.1, 0.2, ..., 0.9 to predict March 2019 demand. Identify the value of alpha that results in the lowest MAD. 7.Find the monthly seasonal indices for the demand values using Simple Average (SA) method. Find the de-seasonalized demand values by dividing monthly demand by corresponding seasonal indices. 8.Use regression to perform trend analysis on the de-seasonalized demand values. Is trend analysis suitable for this data? Find MAD and explain the Excel Regression output...
I need guidance
here is the graph that I just created for #2
FI= \kAl 1. Where k is the spring constant and Al is the change in the length of the spring. This relationship is called Hooke's Law. In your class vou will discuss this in more detail and include direction, and any appropriate offset or discussion of relaxed or equilibrium position. we find the spring constant by applying a force and measuring how far the spring stretches from...
pls help me
An electrical firm manufactures light bulbs that have a length of life that is approximately normally distributed with a standard deviation of 35 hours. If a sample of 50 bulbs has an average life of 730 hours, find a 96% confidence interval for the population mean of all bulbs produced by this firm. Click here to view page 1 of the standard normal distribution table. Click here to view page 2 of the standard normal distribution table....
Please if you don't feel like answering the question, just tell
me the steps and I'll do it on my own. Thank you.
For a bimolecular reaction, A+B---->C, a research scientist
has collected sufficient data to construct time courses. The
scientist incubated reactants A and B together and observed the
formation of product C with increasing reaction time. The scientist
then repeated this in the presence of [A] = 15 M and varied
concentrations of B (All data are provided...
