As we’ve seen, the sun’s energy comes from fusion reactions that combine four hydrogen atoms to produce a single helium atom. Even in the sun’s core, where these reactions proceed most rapidly, the reaction rate is very slow, with only about 6.7 * 1013 reactions per second occurring in 1 cubic meter ofthe core. How much power is produced by these fusion reactions per cubic meter? Compare this number with the 300 W/m3 metabolic power produced by a resting reptile.

At a certain location, the solar power per unit area reaching Earth’s surface is 200 W/m2, averaged over a 24-hour day. If the average power requirement in your home is 3 kW and you can convert solar power to electric power with 10% efficiency, how large a collector area will you need to meet all your household energy requirements from solar energy? (Will a collector fit in your yard or on your roof?)
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?
The average electricity consumption of a house in Gainesville is known to be 1,036 kWh in a month (One month = 30 days). They would like to install solar panels of 30 % efficiency to generate this electricity. Given that the average solar power density in Gainesville is 5.47 kWh/m2/day, how much surface area must the panels occupy? Calculate the result in m² but do not write the unit. Round off you E swer to a whole number (zero decimal place.)
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%.
A woman expends 95 kJ of energy in walking a kilometer. The energy is supplied by the metabolic breakdown of food intake and has a 35 percent efficiency. If the woman drives a car over the same distance, how much energy is used if the car gets 8.8 km per liter of gasoline (approximately 20 mi/gal)? The density of gasoline is 0.71 g/mL, and its enthalpy of combustion is 49 kJ/g. Enter your answer in scientific notation. Compare the efficiencies of the two processes. kJ (driving)/ kJ (walking)
As radioactive plutonium isotopes decay, they generate heat as a byproduct. Pu-239 generates 1.9W/kg of heat. How much heat will 1.25molof Pu-239 release after decaying for three hours? Express this quantity in units of calories. Assume Pu-239 has a molecular weight of 244g/mol.
How many joules of energy is transferred by 3kw?
How many hours of sunlight does it take to capture the same amount of energy stored in 1 L of petrol, if instead of using a tree we use a solar panel?Assume: a tree takes up around 30 m2 of land area; we have a solar panel with the same area as that taken up by the tree; 1 L of petrol contains 34.2 MJ of energy; a solar panel captures energy at an average rate of 50 W/m2 for 12 hours a day. How many hours does it take to capture the required amount of energy? Give your answer to one significant figure.
he metabolic power for typing is 150 W for Lili, not a lot as you know probably. How long does it take to burn off the energy in a slice of apple pie, which energy content is 1680 kJ (400 food calorie), in minutes? (Try to stay active, working/studying in front of a computer is not the best exercise you can do for your body.) Your answer needs to have 3 significant figures, including the negative sign in your answer if needed. Do not include the positive sign if the answer is positive. No unit is needed in your answer, it is already given in the question statement. NOT 187
Photosynthesis converts less than 0.5% of incoming solar radiation into new phytomass. The best annual fuelwood productivity of traditional fast-growing species (poplars, eucalyptus, pines) are no more than 10 t/ha. With the energy density of the dry wood averaging 18 GJ/t. (ha = 104 m²). Now, think about a large eighteenth-century city, which is located near a very large forest, would have required at least 20-30 W/m² of its built-up area for heating, cooking, and artisanal manufacturers. This city was totally dependent on the phytomass fuels. With the annual harvest of 20 t/ha: What is the approximate power density of the harvested phytomass fuel? (t = ton; ha = hectare) 600 (W)/(m²) 1.2 (W)/(m²) 1200 (W)/(m²) 1800 (W)/(m²) 0.6 (W)/(m²)
