Which of the following statements is/are CORRECT?   1. If a reaction occurs at constant pressure, q = ΔH.   2. The change in energy for a system is defined as the sum of the energies transferred as heat and work (i.e., ΔU = q + w).   3. If a reaction occurs at constant volume, q = w

If a cordless phone operates at a frequency of 9.00 × 108 s–1, what is the wavelength of this radiation?

The R Markdown and Jupyter Notebook files include the questions, the empty code chunk sections for your code, and the text blocks for your responses. Answer the questions below by completing either the R Markdown or the Jupyter Notebook file.  You will submit a html file using either the R Markdown or the Jupyter Notebook file.  You may make slight adjustments to get the file to knit/convert but otherwise keep the formatting the same. Once you’ve finished answering the questions, submit your responses in a single knitted file (just like the homework data analysis assessments). There are three Data Analysis questions for this section. You will only submit your responses for the Data Analysis questions in the knitted file. Partial credit may be given depending on your response. Next Steps: Save the .Rmd file/Jupyter Notebook in your R working directory – the same directory where you will download the data file for this midterm exam. Having both files in the same directory will help in reading the .csv file. Read the question and create the R code necessary within the code chunk section immediately below each question. Knitting this file will generate the output and insert it into the section below the code chunk. Type your answer to the questions in RMD file/Jupyter Notebook within each question section. Once you’ve finished answering all questions, knit this file and submit the knitted file as HTML on Canvas. Ready? Let’s begin. We wish you the best of luck!
