- Stan Moneymaker needs 15 gallons of gasoline to top off his automobile’s gas tank. If he drives an extra eight miles (round trip) to a gas station on the outskirts of town, Stan can save $0.10 per gallon on the price of gasoline. Suppose gasoline costs $3.90 per gallon and Stan’s car gets 25 mpg for intown driving. Should Stan make the trip to get less expensive gasoline? Each mile that Stan drives creates one pound of carbon dioxide. Each pound of CO2 has a cost impact of $0.02 on the environment. What other factors (cost and otherwise) should Stan consider in his decision-making?Examine the pros and cons of nuclear energy. Why is continuous nuclear fusion as an energy source being researched so eagerly?On food labels, we can read the food-calories of the product. The food calorie is written as "Cal" and it corresponds to 1.000 calories with the lower case 'c! In summary, one food-calorie - 1 kcal = 1 Cal = 4.186 Joules How many Joules will be released by combustion of 1 kg of rice, if rice has 3,200 food-calories per kilogram? O 1.3 J O 13,395,200J O 13J O 1,340 J
- Estimate how many large maple trees would be needed to run a dishwasher for one year. Assume the dishwasher uses 1.1 ×108Jof energy per year and a large maple tree captures 10 kg of carbon (in CO2) per year. Assume the power plant that generates the electricity is 37 %% efficient at converting the carbon in coal to electrical energy and that typical coal releases 40,000 kg of carbon (as CO2) per terajoule of energy when burned.Wind farms in Washington have a capacity of 3075 Megawatts (mega means million remember so this is 3075000000 watts). This means if they were all operating at the same time this is how many Joules per second they would produce. a) Assume all wind farms in Washington are operating at capacity. How much energy in Kwh is produced in one hour? b) Now it is not windy all the time, so suppose only 60% of the wind farms are operating. How much energy is produced in a 7 day week by these wind farms c) An average home uses about 250 KWh for a 7 day week. How many homes can be operated by the wind farms in part bIn a box model, the maximum distance to transport particle across a city is calculated as follows: Approximate length of one side is 30 miles, width is 28 miles and the mixing height is 2 miles. For a pollutant particle emitted on one side of the town, what is the maximum time it will take to be transported across the city with wind velocity of 10 miles per hour (to the nearest hour)?
- What is the major obstruction to nuclear fusion and why?Thinking Nuclear Power is a perfect example of exponential relations. Canada produces over half of its electricity using nuclear reactors. One of the major problems associated with nuclear power generation is the radioactive waste. Currently all nuclear waste is stored on site at the power plant and there is no solution for the long term waste. After completing this Grade 11 Functions and Applications course, you have been put in charge of Energy Production in Canada. A) What would you do with the long term waste? B) How would you take care of Canada's energy needs for the future?Which property of the Earth's atmosphere causes the greenhouse effect? The Earth's atmosphere allows radio waves to pass through, but it absorbs some ultraviolet radiation. The Earth's atmosphere allows radio waves to pass through, but it absorbs some infrared radiation. The Earth's atmosphere allows visible light to pass through, but it absorbs some infrared radiation. The Earth's atmosphere allows visible light to pass through, but it absorbs some ultraviolet radiation.
- What is the renewability of nuclear power? O It is a nonrenewable energy source. O It can use the same fuel cells repeatedly. O It is an unlimited, clean energy source. O It can be replenished, but not by fusion.The United States has a lot of federally owned land. Unfortunately, uncontrolled natural forest fires destroy large areas in the western US every summer. In 2002, about 1,000,000 acres of standing timber in national forests were consumed. Some consideration is being given to improved management practices that could produce electric power from residual forest thinning. Estimate the lost energy content of burned US forests during 2002. Assuming the US average electricity demand is about 300,000 MWe, how much forested land would be needed to produce all the country's power? Is this a sustainable alternative? How would you manage the forest lands needed? A few facts to consider: • The total forested area on US federal lands in the lower 48 states is about 600 million acres with a standing stock density of about 100 dry metric tonnes of wood per acre, • ● Woody plants and trees capture solar energy via photosynthesis at an average rate of about 0.8 W/m2 which corresponds to producing about…How much land (in km2) would you need to cover with solar panels in order to generate all of our power from solar energy? Assume human power consumption is 15 TW. If one takes into account the day-night cycle and occasional cloudiness, solar panels receive on average about 200W/m2 of sunlight. And this is further reduced because those panels convert sunlight into electricity with an efficiency of about 20%.
