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.
Engineering 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?

Newton’s 2nd Law Lab (Modeling friendly lab) Go to the PhET simulation Forces & Motion. https://phet.colorado.edu/sims/html/forcesandmotionbasics/latest/forcesandmotionbasics_en.html Select “Acceleration” Click to show Forces, Sum of Forces, Values, Mass, and Acceleration. There are two experiments for this activity – make sure you include both. Experiment #1: Acceleration vs. Force In this lab you will determine the relationship between acceleration and net force. Choose a mass at the beginning, and keep it constant for this entire experiment. Set the friction to zero. This will make your Applied Force equal to the net force. Record data for five different values of Applied Force. Graph Acceleration vs. Net Force. Graph this in Google sheets(you want a line graph - it should only have one line). Make sure that Applied Force information is used as the x value Make sure that Acceleration information is used as the y value Add a trendline – see what fits best –…
