A calibration source is found in the lab with the label “60Co, 10 μCi”. The date from when that activity was measured has faded. Your radiation safety office wants to know how old the source is. You measure the current activity to be 0.08 μCi. How old is the source?

Beer’s Law Objective : We will explore an application of absorption spectroscopy using calibration curves and Beer’s Law. Use the “LAB : HOW TO…” link from the class website if you need help with how to use balance, Bunsen burner… and such. Introduction: You may write this information in your lab notebook for your own reference. It can’t be cut and pasted. Different solutions have different spectral properties. In this portion of the experiment those properties will be utilized to...

Q2: At the top are the 3 wavelengths we found. How do you find
which energy levels it transitions between? (ignore most of my
work)
Graded activity: The wavelengths to the side are what we
found. We are also given energy level diagrams for each element. We
believe it’s hydrogen but what work would we do to find this?

1. Dixon is a 43-year-old man with a family history of colon cancer. The physician has suggested that he perform a fecal occult blood test. However, when you discuss it with him he tells you that he is not interested because “there is nothing that can be done about colon cancer anyway.” He is referring to the fact that his father and his brother died of the disease. What should you say to him? 2. Jeffrey is a 15-year-old boy...

Lab Activity 6: Multiple Regression We are looking at the research question: Will positive affectivity (PA) and social support (ASOCS) predict academic burnout (ABO) levels? Previous research has shown that people who have more positive affect tend to experience burnout less. Research has also shown that social support can help prevent burnout. Previous research has not found any relationship between positive affectivity and social support. | Descriptive Statistics Mean Std. Deviation N 3.3154 .92736 227 ABO PA 3.356 .6729 227...
