Once on this page, check the "angles" box in the bottom left hand corner.
The index of refraction for the bottom material is automatically set to glass. Turn the laser on by pressing the red button. Answer the following questions:
1. If you were to slide the button down to the left for this material, do you expect the angle of refraction to increase or decrease? Why?
Put the bottom material back to glass. Change the top material to "Mystery B" in the drop down menu.
2. What is the index of refraction of this material? How did you figure this out? You can check your answer by switching the material to Custom.
3. Do you expect the light to be moving faster in the top material or the bottom material? Why?
Switch the option in the top left corner from "Ray" to "Wave". Check your answer by dragging the speed tool over both laser paths to see if you were correct.
4. If you tilt the laser to an angle greater than 46%, what begins to happen?

GEOL1202 UCDenver Greenhouse Gas Emissions & Household Energy Demand
These are all instructions and Explanations associated with this assignment. During this tutorial you will:
Calculate the electricity demand for a householdCalculate the amount of fuel consumed to generate this electricity using non-renewable sources of energyCalculate the greenhouse gas emissions for each fuel type and generation methodInstructions and explanations:
On the Energy Demand Sheet
fill in the number of units for each item you haveand the average number of hours of use per day.Keep in mind how your use may change through the year, and factor this into your daily use. Constantly-running units have typical hours of use already filled in (fridge, water heater, furnace). You may enter fractions of hours (ie. 15 minutes is 0.25 (one quarter) hour).Calculate daily energy demand (in units of Watt-hours)
Multiply the number of units by the number of hours of use, then by the power demand.At the bottom of the table add all of these together to calculate the total daily electricity consumption.Complete the conversions at the bottom of the table. Transfer the individual annual electricity demand to the Fuel Consumption WorksheetNon-renewable fuels are a form of potential energy. Each fuel type has its own energy density, or the amount of energy available to be released for a certain quantity of fuel. The energy densities of Fuels are given on this worksheet.(Notes: 1. m^3 = cubic metre, a measure of volume. 2. CANDU is the type of nuclear generating facility designed and used in Canada.)Conversion of energy from one form to another always results in some energy being dissipated (or lost), usually as heat. The efficiency of this conversion of energy depends mostly on the technology employed. The table on this page shows the efficiency of generation as a proportion of the total potential energy. For example, if the efficiency of generation is 0.35, this means that 35% of the energy of the fuel is transformed into electricity (or 65% of the energy of the fuel is lost).
To adjust the energy density of the different fuels for the efficiency of electricity generation, multiply the energy density by the efficiency of generation.(Note: In combined cycle generating facilities, a gas turbine uses the hot gases released from burning natural gas to turn a turbine and generate electricity. The waste heat from the gas-turbine process is used to generate steam, which is then used to generate electricity.To calculate the amount of fuel required to satisfy your annual household energy demand
divide your household energy demand (MJ) by the energy density adjusted for efficiency. (demand/density=fuel required)Step 7. Calculating the GHG
Use the GHG emissions worksheet 2016- Take the fuel required from each liquid or solid fuel type (e.g. Diesel (steam driven)) and multiply it by the emission factor. This will give you the emission in grams.- Then multiply this by the CO2 equivalent factor (CH4 has more warming potential than CO2).- (Co2 = 1, CH4 = 23, N20 = 317)- There are different values in the literature for these equivalent factors so if you used different one that is ok. I have included them in the version 2 of the GHG worksheet. This will give you the CO2 Eq in grams.- Add up the three CO2 Eq values for a total of CO2 Eq (g)- Divide this value by 1,000,000 to give you the value in tonnes.

Chronic Obstructive Pulmonary Disease (COPD)Required ResourcesRead/review the following resources for this activity:TextbookWeekly ConceptsMinimum of 1 scholarly source (Not older than 2016)Scenario/SummaryHector loved visiting and playing with his grandson, David. Today was David's birthday and the whole family was at the park to celebrate. They had tons of food and lots of games to enjoy. At one point, they had a three-legged race and David asked his grandfather, Hector, to be his partner. They gave it everything they had and crossed the finish line ahead of everyone else for the win.Afterward, Hector started wheezing and had trouble catching his breath. He also had a tightness around his chest. Fearing that Hector may be having heart troubles, the family rushed him to the local emergency room. Hector reported to the doctor that he had been having a chronic cough that he couldn't get rid of and had to clear his throat of mucus every morning.Respiratory function tests indicated that Hector had Chronic Obstructive Pulmonary Disease (COPD) as a result of chronic bronchitis. The ER physician sent him home with some medication and advised hector to assume the tripod position to aid in his breathing when he was experiencing shortness of breath.DeliverablesAnswer the following questions and save your responses in a Microsoft Word document. Provide a scholarly resource to support your answers.How is ventilation different from respiration?Ventilation is dependent upon a pressure gradient. Describe how this pressure gradient works.What muscles are involved in ventilation?What is COPD and how does it affect ventilation?How does the tripod position help breathing in COPD patients?
