Concept explainers
You use the data from the Mauna Loa observatory in the previous question to create the following histogram and COF. These data reflect the observed yearly increase in CO2 emissions for the past 51 years. The annual mean rate of growth of CO2 in a given year is the difference in concentration between the end of December and the start of January of that year If used as an average for the globe, it would represent the sum of an CO2 added to, and removed from the atmosphere during the year by human activities and by natural processes.
Note
In the graph the locations of A-E are approximate. In other words, you cannot guess the value based upon the graph—you must calculate the value.
a. What is the value of point A?
b. What is the value of point B?
c. What is the value of point C?
d. What is the value of point D?
e. What is the value of point E?

- 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 –…arrow_forwardPosted below is a picture of a data table and a diagram of an experiment. In the experiment you rolled a marble down a ruler ramp off the end of a coffee table to observe projectiles and conservation of energy. You do 3 trials for each initial height. Each height is measured in meters. h= initial height of marble off of table Y= height of table off floor X= horizontal distance marble goes from edge of table to where it strikes the floor a) use the table to find information you need to solve for theoretical range and % of error in measured range.arrow_forwardPlease 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_forward
- Please help answer the question shown in the photo. Please explain clearly why the formulas you picked were used, and what the purpose of each number and variable in your calculation represents. Thank you!arrow_forwardTHERMODYNAMICS UPVOTE WILL BE GIVEN. PLEASE WRITE THE COMPLETE SOLUTIONS/DIAGRAMS LEGIBLY. NO LONG EXPLANATION NEEDED. USE 3 DECIMAL PLACES. BOX THE FINAL ANSWER. 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_forwardHi please help with this question thank you I just can't seem to work it out even with the given formulas. Thanks! also, I have tried these but they seem to be incorrect, or maybe parts of the calculation may be incorrect since when I submit these all together and I can't really work out where I am going wrong: sigma x = 25.43 sigma y = 13.07 Txy = 49.124arrow_forward

So far I have calculated and tried to input the following values: 1 hp, 1.01 hp, 0.8 hp, and 12.53 hp, 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. Thank you!arrow_forwardHi.

So far I have calculated and tried to input the following values: 1 hp, 1.01 hp, and 0.8 hp but it always keeps saying they are incorrect. Am I missing a sign change? (Should the answer be negative?)

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 as requested in the question (writing the x and y components of the equation and solving the equations for the unknowns). Below 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 this 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_forward
