Question

1. which of the following resources produces the least pollution? a. solar energy b. natural gas c. nuclear energy d. petroleum 11. nuclear power plants use a process called? to produce energy. a. fission b. fusion c. fractionation d. none of the above 12. a solar - powered calculator uses a. solar collectors. b. solar panels. c. solar mirrors. d. solar cells. 13. which of the following is a problem with using wind energy? a. air pollution b. amount of land required for wind turbines c. limited locations for wind farms d. none of the above 14. dung is a type of a. geothermal energy. b. gasohol. c. biomass. d. none of the above

Explanation:

1. Solar energy is a clean - energy source with minimal pollution. Natural gas, nuclear energy, and petroleum have more significant environmental impacts in production, use, or waste management.
2. Nuclear power plants use the fission process to split atoms and release energy. Fusion is not yet commercially viable for power generation in the same way, and fractionation is a separation process in refining, not related to nuclear power production.
3. A solar - powered calculator uses solar cells to convert sunlight into electricity. Solar collectors are for heating fluids, solar panels are made up of multiple solar cells and are larger - scale, and solar mirrors are used for concentrating sunlight in some power plants.
4. Wind energy has limitations such as the need for large amounts of land for wind turbines and limited suitable locations for wind farms due to wind resource availability. It does not cause air pollution during operation.
5. Dung is a type of biomass as it is organic matter derived from living organisms and can be used as a source of energy. Geothermal energy comes from the Earth's heat, and gasohol is a blend of gasoline and ethanol.

Answer:

1. a. solar energy
2. a. fission
3. c. solar cells
4. b. amount of land required for wind turbines, c. limited locations for wind farms
5. c. biomass
