Referring to the previous ICA 13-5, Angus is also testing a voltage-controlled oscillator. In this case, a control voltage (also between –5 and +5 volts) changes the frequency of oscillation in order to generate different note. The table below shows these measurements. Show the resulting data and trendline with equation and R2 value on the appropriate graph type (xy scatter, semilog, or log–log) to make the data appear linear.

- PLEASE ANSWER THEM ALL FOR AN UPVOTE. THANK YOU. Given: Pi constant to be used: 3.14159 Capillary tube: radius = 0.02 cm; length = 9 cm; pressure = 0.7 mmHg Liquid sample: density = 4 ml; time of flow = 4.5 seconds Ans. the ff questions. •What is the pressure in MKS unit? •What is the pressure in CGS unit? •What is the viscosity of the liquid? • If the weight was given as 8.5 grams, what will be the density of the liquid? •What is the kinematic viscosity of the liquid? •What is the fluidity of the liquid?arrow_forwardEngineering Economy A company has determined the price and the monthly demand of its products are related by the equation D = √775 - p, where p is the price per unit in dollar and D, is the monthly demand. The associated fixed costs are $2,125 per month and the variable costs are $100/ unit. Use this information to answer the following: a)What is the optimal number of units that should be produced and sold each month? b) What is the maximum profit? c)Determine the value of D that represents the break-even point?arrow_forwardYou own a wheat warehouse with a capacity of 20,000bushels. At the beginning of month 1, you have 6,000 bushels of wheat. Each month, wheat can be bought and sold at theprice per 1000 bushels given in Table 46.The sequence of events during each month is as follows:a You observe your initial stock of wheat.b You can sell any amount of wheat up to your initialstock at the current month’s selling price.c You can buy (at the current month’s buying price) asmuch wheat as you want, subject to the warehouse sizelimitation.Your goal is to formulate an LP that can be used to determine how to maximize the profit earned over the next 10monthsarrow_forward
- Please provide equations that you are using so I can follow along and learn how to do this and include conversions and units. In Jamestown, NY, a coal power plan consumes coal at a rate of 80 tons/hr. When coal burns, it generates approximately 30,000 kJ for every kg of coal burned. The cooling course for the plant is the nearby Chadakoin River nearby and, by code, the power plant cannot reject more than 13.19 x 109 MJ into the river annually. Determine the maximum average power output of this plant and it's maximum thermal efficiency. To check your work, enter the efficiency, as a decimal, in the box provided.arrow_forward2. (If relevant) A clearly labeled diagram (or diagrams) clearly pertaining to your analysis with a coordinate system and relevant labels. Final answer with appropriate units and significant figures. You can use the fprintf() command in MATLAB to format numerical results A 2-3 sentence reflection on your answer. Does it make sense? Why or why not? What are some implications?arrow_forwardAs the potential across the resistor increased, the current through the resistor increased. If the change in current is proportional to the voltage, the data should be in a straight line and it should go through zero. In these two examples how close is the y-intercept to zero? Is there a proportional relationship between voltage and current? If so, write the equation for each run in the form potential = constant x current. (Use a numerical value for the constant.)arrow_forward
- Please solve question 16-109 below this in the follwoing way: Please include a kinamatic diagram (one for velocity and one for acceleration). Please DO NOT solve this using velocity analysis (cartesian vector analysis). I would like it to be solved using scalar method. We dont use 3D in this course. We only use scalar analysis for the relative velocity equation (writing the x and y components of the equation and solving the equations for the unknowns). I have attached a sample question with solution in order to get an idea on how to use the scalar method to solve my question. I would like question 16-109 to be solved in a similar way. Thank you for your understanding. If you can solve it as soon as possible that would be great and I will give you a thumps up and positive feedback :)arrow_forwardHi. I am trying to practice this problem using a checker online, but everytime I recalculate my answer it always says it's incorrect. So far I have calculated and tried to input the following values: 0.0342 m3/s, 0.0358 m3/s, 0.04277 m3/s, and 0.0555 m3/s but it always keeps saying they are incorrect. Please help show me the correct steps on how to get the correct answer as I am trying to learn this process.

- Hi. I am trying to practice this problem using a checker online, but everytime I recalculate my answer it always says it's incorrect. So far I have calculated and tried to input the following values: 0.0342 m3/s and 0.0555 m3/s but it always keeps saying they are incorrect. Am I missing a sign change? (Should the answer be negative?) Or am I solving this incorrectly and getting the wrong value each time?

An airplane is cruising at an elevation of 35,000 feet from sea level. Determine the amount of gage pressure in bars needed to pressurize the airplane to simulate sea level conditions. The average atmospheric pressure on earth is mated as a function of altitude by the relation Patm = 101.325 (1- 0.02256z)5.256, where Patm is the atmospheric pressure in kPa and z is the altitude in km with z = 0 at sea level.arrow_forward
