- What is a benefit of using bioenergy over nuclear energy? O Bioenergy uses less water and land, reduces waste. O Homeowners will see large cost savings over time. O There is little to no installation cost to use bioenergy. O Bioenerg does not release harmful greenhouse gases.5. For most automobiles, the number of miles per gallon decreases as highway speed increases. Fuel economy drops as speeds increase from 55 to 65 mph, then decreases further as speeds increase to 75 mph. Explain why this is the case. Please state the following (apply your problem solving strategy): A. REASON: State and describe the overall physical principles you think apply to solve this problem. 3. ASSESS: What is the energy content in kJ of gasoline in 1 g of fuel?3. Two of the emerging technologies in reducing automobile emissions are electric cars and hydrogen fuel cars. Both work by converting chemical energy to electrical energy then to mechanical energy. However, electric cars require charging stations, while hydrogen fuel cars require refilling stations. Which technology is better? Why?
- What is nuclear energy? Discuss the types of nuclear energy. Explain how nuclear energy can be used for constructive and destructive applications.32.) In the United States most of the fuel used comes from a classification called fossil fuels. What does fossil fuel refer to? a. fuel that formed from ancient plant and animal life, representations of which are sometimes found as fossil imprints b. a technique known as fossilization that must be used in order to obtain energy from these fuels embedded fossil remains in the fuel itselfIf fossil fuels,such as coal,are still forming today,why are they considered nonrenewable resources? A. We are depleting fossil fuels much faster than they form B. Fossil fuels are broken down by processes faster than they form C. The fossil fuels being formed today are deep under the ocean, where they cannot be reached D. The only fossil fuels being produced are from methane, which we do not have the technology to use yet.
- What is nuclear energy? Explain the working of a nuclear reactor? Provide three disadvantages of nuclear energy?1.) Natural gas is the most abundant fossil fuel in the world. a. True b. FalseSome people think nuclear energy is good and should be used widely for energy production. Other people think it should not be used at all. Do some research on nuclear energy to determine its positive and negative impacts on society and the environment. Your opinion piece should have the following: An opening sentence stating the issue. A description of the various stakeholders on this issue. One paragraph on the positive impacts on society and the environment and which stakeholders are for it. One paragraph on the negative impacts on society and the environment and which stakeholders are against it. One paragraph on your position on this issue, with a description of your reasoning. A closing sentence that sums up your argument.
- Before an earthquake hits, the University of Ruritania (UR) had rooms enough for 5000students, which it rented at $300 per month per student. At that price, 500 students whowanted rooms on campus had to be turned away.a. The earthquake damages 1000 rooms, and it will take one month to make repairs. Graphwhat the earthquake does to short-run supply and demand for on-campus rooms.b. After the repairs are made (taking the total rooms back to 5000), UR decides to constructadditional housing for 1050 students (which will raise the total to 6050). It plans to lowerthe price for rooms so that all rooms are occupied. About how much will rent be if theelasticity of demand is -4? How about -2? How about -.2? In which case would the newhousing increase university rental revenues the most?c. How is your calculation in b) affected if rent is set in Ruritanian clochemarks($1=2.75cm) instead?I am having a hard time understanding question 23, I have done some work so far but I don't know if I am doing it rightDIFFERENTAL EQUATION: GROWTH AND DECAY, NEWTON'S LAW OF COOLING AND DILUTION/MIXING PROBLEMS. Show COMPLETE SOLUTION. 4. In a Science class experiment, the population of insects increases according to the law of exponential growth. There were 150 insects after the fourth day of the experiment and 395 insects after one week. a. Approximately, how many insects were in the original population?b. Compute the number of insects after 10 days.
